Super delicious and easy meringue roulade dessert!

I usually bake a large roll of 8 egg whites and even this is not enough for us since it is such a tasty and light dessert. If desired, you can bake with less protein and sugar.
The calculation is that for 1 white (large egg) there is 50 grams of sugar.
8 proteins (270g)
A pinch of salt
400 g fine sugar
2 tbsp cornstarch
For cream:
300 grams of cold cream at least 30%
2 tbsp fine sugar or powdered sugar
For the raspberry layer
