Sift the flours into a bowl. Add baking soda, stir to combine and set aside.
Preheat the oven to 250°C. Prepare 6 ramekins or a muffin tray, grease it with oil.
Separate egg yolks from egg whites. Beat the egg whites into a foam.
In a separate bowl, mix the egg yolks with sugar, using the electric mixer, then combine with oil and vinegar – mix until smooth. Then, add in small parts a little bit of water and a little bit of sifted flours – continue until you’ve used up all the ingredients, stirring continuously until everything is combined.
Add the egg white foam and stir it in gently with a wooden spoon.
Place the dough evenly in the ramekins and sprinkle with sesame seeds. Bake for 10 minutes, then change the temperature to 200°C and bake for another 20 minutes.
