With pleasure.
- 75 ml of water
- 75 ml of milk
- 35 g of butter
- 1 table spoon of sugar
- a pinch of salt
- 70 g of flour
- 3 eggs
- 50 ml of vegetable oil (I used olive oil, worked perfectly fine)
- 5 egg whites
- 80 g of sugar
First things first, take 5 eggs and separate them on whites and yolks. Do whatever you want with yolks, but keep whites around, you will need them later.
Preheat oven to 180 degrees Celsius. Meanwhile, beat three whole eggs a little and put aside, then sift flour into a separate bowl and put aside too. Put water, milk, sugar, salt and butter into stewpan over medium heat. When butter melts bring it to the boil, then add sifted flour in one go. Turn heat to the minimum (or turn it off, if your stove keeps heat well enough) and whisk your dough (you can use fork like I did, since my whisk is prone to falling apart) until it becomes one ball that doesn't stick to the bottom and sides of the pan. Then put it into cold bowl and mix it with a spatula to cool it off a little, until it becomes warm instead of hot. Then add three beaten eggs in 3-4 portions into the dough and whisk them until combined. Then finally add vegetable oil and whisk together too.
When it's done, take your 5 egg whites and whisk them till they turn into foam. Then little by little add 80 g of sugar while whisking until you get steady peaks i.e. you take your whisk out of your meringue and the "bird beak" doesn't bend when you point it upwards. After this add third of your meringue to the dough and fold it in with a spatula. Then another third and then what's left.
After this pour your dough on the baking sheet and flatten it with spatula or whatever you like. Keep in mind, that it will be twice of the volume of the ingredients, so you should be ready to bake two rolls instead of one. Bake for 12-14 minutes, it depends on your oven, just till it becomes a little golden-brown (although I'd argue that you can bake it just a little more). After it's done take it out, put another baking sheet on top of it and turn it over. Even thought it is way more elastic than sponge cake, I'd recommend you to roll it right there, while it is hot. Put a filling of your choice on top of it - jam, cream, curd, peanut butter, chocolate paste, whatever, I've made lemon curd since I didn't want to throw away yolks -, smear it around and gently roll it, while squeezing it enough so there would be no gaps. Then dust it with powdered sugar or cover it with glaze - you decide.
Thanks and bon appetit!
