Flourless Lemon & Raspberry Swiss Roll

by Susan Smith in


I have to say, this light and airy, low-carb, grain-free, refined sugar-free and fat-free Swiss roll cake mix is probably the best Primal/Paleo cake I’ve ever made! Rightly so, because I made it for my daughter Sarah’s birthday on 4th July, and she is most definitely worth it. 

The night before her birthday, I was slightly panicked as to how I was going to bake a birthday surprise at such short notice. I’d bought in a stack of fresh summer fruits - just in case I could conjure up something fabulous - but the idea for this impressive looking, light-as-a-feather cake didn’t come to me until about ten 'sleep-hours' before Sarah was due to come over the following morning to unwrap her presents.

Baking an impromptu, untried, made-up recipe for a special occasion isn’t normally my bag, but since only cake will do when there’s a birthday to celebrate I got up early the next morning with my fingers crossed. I am so glad I did. This beautiful cake is not nearly as daunting to make as it looks and the finished result is so light in texture and tastes so fresh that it cannot fail to delight anyone lucky enough to share it. In fact, it is so good, four of us couldn’t restrain ourselves from eating the whole cake in one sitting. Furthermore, as Sarah’s elder sister hadn’t been there for the birthday party itself, it was a great excuse to bake two of these cakes on consecutive days! Once you try this light and lovely treat, you’ll understand why we find this delicious lemon and raspberry Swiss roll totally irresistible.

On the face of it, I should probably consider myself ‘caked-out’ for now, however the truth is, I’m actually motivated to seek out more people whose birthday is imminent! As there’s nothing unhealthy about this Flourless Lemon & Raspberry Swiss Roll, you really don’t need an excuse to indulge. If you love someone enough to want to bake them cake, this one’s gorgeous good looks and lemony, raspberry goodness is all you need to impress.

Flourless Lemon & Raspberry Swiss Roll (makes 12 slices)

Ingredients - for the Swiss roll

4 large organic free-range eggs, separated

40g Sukrin:1 granulated sweetener

40g organic ‘runny’ honey (I actually used raw unpasteurised honey and gently heated it to make it runny)

Zest of 1 organic lemon, finely grated

75g organic ground almonds                            

25g organic tiger nut flour

½ tsp baking powder

1 tbsp Sukrin icing sugar - for dusting top of cake

 

Ingredients - for the raspberry sauce

150g fresh raspberries

75g no added sugar raspberry spread

 

Ingredients - for the lemon cream

125ml organic double cream

1 tbsp Sukrin icing sugar

Zest of 1 organic lemon, finely grated

 

Instructions

Butter and line a 22.5 cm x 32.5 cm (approx. 9” x 13”) Swiss roll tin with non-stick baking paper. 

Preheat the oven to 180°C / 350℉ / Gas mark 4

Sift the tiger nut flour and baking powder together into a bowl and then add the ground almonds. Stir to combine.

If using ‘set’ honey, place in a small saucepan over a very gentle heat until it liquefies. Take off the heat and allow to cool down for a couple of minutes.

In a medium/large bowl, whisk the egg whites until stiff. In a separate large bowl, whisk the egg yolks, the lemon zest, Sukrin:1 and 'runny' honey until light, airy and mousse-like i.e. very pale and thick – this will take about 3 minutes using an electric whisk on high speed.

Stir the ground almonds and tiger nut flour into the egg yolk and lemon zest mixture. 

With a rubber spatula, gently fold in the egg whites, a third at a time, until completely mixed in.

Pour the mixture out onto the lined baking tray and bake for 10-15 minutes until golden, firm and springy (mine took exactly 13 minutes).

Remove from the oven and leave in the tray to cool, covered with another piece of baking paper and a damp tea towel.

To make the raspberry sauce: In a small saucepan set over a low heat, cook 75g fresh raspberries with the raspberry spread. Bring to a gentle simmer, then using the back of a fork, crush the raspberries down into a sauce. Take off the heat and set aside to allow the sauce to cool down completely.

To make the lemon cream: Whip the cream with 1 tablespoon of Sukrin icing sugar and the lemon zest until almost thick i.e. stiff but still speadable. Cover and keep in the refrigerator until you’re ready to assemble the cake. Cut the remaining raspberries in half.

When the cake is cool, remove the tea towel and parchment paper and lay them down flat onto a work surface - with the non-stick paper sat on top of the tea towel. 

Generously dust the top of the sponge with Sukrin icing sugar then flip it out onto the parchment paper with one of the short edges facing you. Carefully peel the baking parchment off the cake.

With a small sharp knife score a line 2 centimetres in from the short edge nearest to you - making sure you only cut about halfway through the depth of the sponge. 

Next, spread the raspberry sauce all over the top of the cake to within about 2 centimetres of the edge. Then layer the whipped lemon cream on top of that - again leaving a 2 cm edge all the way around. Finally, dot the raspberry halves evenly on top of the cream. 

Start rolling the cake up tightly from the short end where you scored a line. Using the parchment paper to help you, keep rolling tightly until you get to the end. Carefully lift the Swiss roll onto a plate with the seam side down.

Chill for 30 minutes before serving.

 

Notes

Aside from Sukrin’s stevia/erythritol sweetener, the best natural alternative sweetener for baking is organic maple syrup because it is not chemically affected by heat. However, whilst testing this cake recipe out I didn’t want to risk maple syrup’s distinctive taste coming through, so I chose to use honey.

Using half honey and half Sukrin:1 to sweeten this delicate sponge minimises the potential aftertaste when using stevia alone. Whilst the vast majority of honey available in the shops has already been subjected to heat - so it makes no difference whether you decide to heat it or cook with it at home - this is not true of Na’vi’s wonderful, raw, unpasteurised honey. Heating Na’vi’s honey is sacrilege! It destroys many of its beneficial effects, killing off its ‘superfood’ status. If you’re going to buy Na’vi honey - and I recommend that you do - simply enjoy its health-giving benefits spooned straight from the jar. It was Hobson’s choice that I used it for my cake because it’s the only honey I ever keep in my store cupboard!

Summer Berry & Lemon Cream Tigernut Tart

by Susan Smith in , ,


This week was the start of Wimbledon (think strawberries and cream) and culminates in Independence Day (Saturday, 4th July) - think, ‘Happy Birthday’, to my beautiful daughter, Sarah! After that Mirror Imaging is into a run of photoshoots and weddings on five consecutive weekends that will keep us both busy until the end of September. So with that in mind, I really wanted to make an extra special summer birthday ‘cake’ for Sarah, not only to celebrate her birthday but also the last of our leisurely weekends for the foreseeable future!

Today, I am so excited to be able to bring something completely new to the party - a delicious summer fruit tart made with tiger nut pastry. “Tiger, erm what?”…I hear you say!

Q. When is a nut not a nut? A. When it’s a tiger nut! 

Tiger nuts, also known as ‘earth almonds’ and in Spain, ‘chufas’, are the sweet, brown, nutty, ‘super’ tubers of the sedge plant (a stubborn, weed-like grass), which is grown and harvested like potatoes. And, they are incredibly good for you. 

Truly Primal/Paleo (our early human ancestors used to forage and feast on this nutrient dense wonder food), tiger nuts have a nutritional profile that really holds its own against red meat, olive oil and even human breast milk. In fact, tigernut milk (recipe for Spanish style ‘Horchata de Chufas' coming soon) is the healthiest substitute for dairy milk because it is rich in monounsaturated fat and does not contain inflammatory omega-6 fatty acids like other nut milks do. Tiger nuts are also full of dietary fibre, particularly resistant starch, are high in minerals (magnesium, phosphorous, potassium, calcium and iron) and Vitamins C and E. Sounds to me like the under-utilised tiger nut might well be the answer to 795 million people around the world still struggling with hunger and malnutrition! 

And, in modern society, where people are often overfed and under-nourished, research suggests that tiger nuts can help reverse or stop the progression of degenerative diseases such as  diabetes, heart disease, circulatory problems, digestive disorders, autoimmune diseases and some cancers, including colon cancer.

I’ve only just re-discovered tiger nuts (they were sold as sweets when I was little) as part of my ongoing search for grain-free, gluten-free and now nut and allergy-free alternatives to grain flours. To say I’m chuffed with the way my chufa pastry lined Summer Berry & Lemon Cream Tigernut Tart worked out, is an understatement! This new kid on the block for lovers of Primal/Paleo treats, ticks all the boxes for healthy, nutritious food that makes you glad to be alive - indeed a little bit smug - because who would guess that this gorgeous Summer Berry & Lemon Cream Tigernut Tart would be entirely compatible with a low-carb, refined sugar-free diet?

When cooked, this tigernut pastry has more the taste and texture of a biscuit cheesecake base than it does shortcrust pastry per se, but I like this. As pastry goes, it’s very user friendly. It rolls out like pâte sucrée (French name for sweet shortcrust pastry) and was incredibly well behaved when I lined the flan case - although a chunk fell off one edge when I lifted my rolled pastry disk off the work surface, it was easy to patch up and press everything back together again with my fingers, once it was in the tin. 

Best of all, because tiger nuts are naturally sweet, you don’t need to add sugar or other sweeteners. I’ve been wanting to devise a recipe for Primal cheesecake for some time, so when I do I’m certain this recipe will double-up, adapting itself to both sweet tarts and cheesecakes beautifully.  

Meanwhile, I hope you’ll make the most of summer’s juiciest berry-fruits in this exceptionally lovely looking tart - I think summer celebrations will be the sweeter for it. 

Summer Berry & Lemon Cream Tigernut Tart (Serves 10)

Ingredients - for tiger nut pastry

225g tiger nut flour (available online from The Tiger Nut Company)

1 tsp baking powder

2 tsp pure vanilla essence

30g unsalted butter, melted

1 large organic egg, beaten

a little extra melted butter (about 5g), for greasing 

 

Instructions - to make the pastry case

Pre-heat the oven to 180℃ / 350℉ / Gas mark 4.

Grease the base and sides of an 8 inch loose-bottomed fluted flan tin with melted butter.

Combine the tiger nut flour, baking powder and vanilla essence in a bowl.

Mix in the melted butter, then add the beaten egg and stir with a fork to combine.

When roughly combined, abandon the fork and bring the mixture together with your hand to achieve a firm but moist dough. 

Roll out to a round thickness of 3mm-6mm between two sheets of plastic cling film (to avoid the dough sticking to your worktop or rolling pin). As you roll, turn regularly to achieve an even round shape that is approximately 2½cm/1” larger than the circumference of your tart tin (this allows for the sides of the tart). 

Carefully peel off the top layer of cling film, then loosely wrap the pastry around your rolling pin removing the bottom layer of cling film as you do, then using the rolling pin to support the pastry, lift it one piece directly into the tart tin. If it splits or breaks in transition (mine did!), don’t worry, just patch it back together by pressing it firmly and evenly into the base and up the sides of the tin with your hands. N.B. Since tiger nut flour is gluten-free it’s easier to handle than normal shortcrust pastry, because it doesn't get harder and tougher if you need to re-work it. Once it’s settled in the tart tin in an even thickness, trim any raggedy bits of pastry off the top edge by going around with a sharp knife (chef’s privilege to eat these pastry off-cuts raw!)

Prick the base of the tart all over with the prongs of a fork. 

Bake for about 12-15 minutes, or until lightly browned and crisp. Leave to cool completely in the tin before transferring to a serving plate.  

 

Ingredients - for lemon cream filling

150ml Primal Lemon Curd

150ml Crème Fraîche (I used Roddas)

150ml Double Cream

 

Instructions - to make the lemon cream filling

Put all the ingredients into a bowl and whisk until the mixture thickens and will stand in soft peaks.

Cover and store in the refrigerator until you’re ready to assemble your tart. 

 

Ingredients - for fruit topping

250g fresh strawberries, picked over and cleaned as necessary

175g fresh raspberries 

100g fresh blueberries

A few sprigs of fresh mint or lemon balm, to decorate

 

Instructions - to assemble the tart 

Not more than an hour before serving the tart, place the pastry case onto a serving plate. 

Spoon the lemon cream filling into the tart case and spread out evenly.

Arrange the fruit attractively on top of the lemon cream filling, then garnish with sprigs of fresh mint or lemon balm. 

Notes

Although this tart looks like ‘fancy-pants’ French patisserie, please do not be intimidated by the recipe. Rolling out the pastry and lining the tart tin is the only challenge - and only then for the novice cook. Everything else is quick and easy to do - including making the pastry and assembling the tart. If you need to, just follow the photographs for how to arrange the fruit topping.

I suggest you make a batch of yummy Primal Lemon Curd up to several days in advance (in readiness for the lemon cream filling) and store (hide!) in the refrigerator until you’re ready to assemble your tart. 

I like the visual treat of using several different types of summer berries as the topping for this tart - and the particular selection I’ve chosen all marry well with the lemon cream filling. However, just one type of fruit (blackberries, cherries, sliced peaches, apricots, etc.), or any combination you like, will work. Just select the sweetest, juiciest and most visually appealing fruit you can find.

Refrigerated in an airtight container, this tart still eats really well the next day.
