Fruit and Custard Swiss Roll

In a bowl, combine the eggs, milk, and sugar, then add a pinch of salt and the flour.

Mix everything thoroughly and beat well.

Pour the batter onto a baking sheet lined with parchment paper and spread it out evenly.

Bake in a preheated oven at 180°C (350°F) for 20 minutes.

For the custard, whisk together the eggs, sugar, milk, and starch, mix well, and place over heat.

Cook until thickened, stirring constantly, then remove from the heat and let the custard cool.

Carefully peel the parchment off the baked sponge cake right away and roll it up while still hot, then set aside to cool.

Unroll the cooled sponge, spread the custard evenly over it, and top with finely diced fruit.
