During the holidays, my daughter asked me if we could make trays like the ones you usually find in the supermarket. She thought it had been a long time since I had done one. There, I can only agree with him! I didn’t even remember how easy and quick they were to make.
It is quite simply a sponge cake that is scored when it comes out of the oven and then garnished with fruit jelly. I chose the blackberry one.
2 good tbsp of blackberry jelly
1 pinch of agar-agar
Preheat the oven to 180°C.
Whisk the egg yolks and 30 g of sugar for a few minutes, until you have a very foamy mixture.
Whisk the egg whites until stiff.
Add the remaining sugar in batches, as soon as the whites start to stick together.
Add a nice spoonful of whites to the yolks. To mix together.
Sift the flour over it. To mix together.
Gently add the remaining egg whites with a spatula.
Divide the batter into 15 silicone molds in the shape of trays.
Cook for 11 to 12 minutes.
As soon as it comes out of the oven, mark the centre.
Mix the jelly and the agar-agar then put the whole thing in the microwave, taking care to boil.
Leave to cool then fill the trays.
To finish: if you don’t have molds in the shape of trays, you can also use molds like small tartlets or even muffins and mark the center with for example a cork. It will no longer be punnets, but it will be just as good.
Agar-agar is not essential if the jelly holds together well. On the contrary, if it is relatively liquid, it will take a little more than a pinch.
