Strawberry Swiss Roll

Instructions

Cake

1. Preheat oven to 175 degrees Celsius.
2. Spray a large square baking pan (30x45 cm approximately), and line with baking paper.
3. In a medium bowl, whisk together the egg yolks, oil, milk, vanilla extract, two-thirds cup of sugar, and lemon zest.
4. In a small bowl, whisk together the gluten free flour, cornflour, baking powder and salt.
5. Stir the dry ingredients into the wet just until combined.
6. In a clean medium bowl, beat egg whites on med-high until soft peaks form (1 to 2 minutes). Add the remaining one-third cup of sugar and continue beating on med-high speed until stiff peaks form (another 1 to 2 minutes).
7. Fold egg whites into the batter until fully incorporated.
8. Pour batter onto prepared baking sheet and bake for 15 minutes or until the top of the cake is light brown.
9. While the cake is baking lay a thin clean tea towel on the counter. Sprinkle with icing sugar. Once the cake comes out of the oven invert it onto the towel. Peel off the baking paper, then starting with the narrow end begin rolling up the cake with the towel. Do this slowly and gently. The cake will be warm. Allow the cake to cool completely rolled up in the towel. You can do this for about 2 hours in the refrigerator.

Filling

10. In a large bowl, beat the heavy cream on high speed until soft peaks form.
11. Add the sour cream, vanilla extract, and icing sugar. Continue beating until stiff peaks form.
12. Remove the cake from the refrigerator and allow to sit on the counter for a few minutes to warm up. When ready to use, gently and slowly unroll the cake. Flatten it out.
13. Spread cream mixture onto the cooled cake leaving a 3 cm border around the edges.
14. In a small bowl combine the strawberries, one tablespoon of sugar and lemon zest.
15. Scatter strawberries over the top of the whipped cream.
16. Starting at the short end, roll up the cake, tightly without the towel this time. Allow to set in the fridge for 20 minutes before serving.
17. Place the cake seam side down. Dust with icing sugar if desired.
