First of all, a brief explanation of why I have set two shortcrust pastry recipes:
I always make double the amount of shortcrust pastry and freeze half of it or I use the other half for another cake (e.g. cheesecake, plum cake, cake cake, apple cake, etc.). Then I only did the job once and quickly made another cake. I have listed the shortcrust pastry in the recipe in the list of ingredients.
I always take enough fruit that I can fill it just below the shortcrust crust. But everyone can do it according to their taste.
Preparation:
Knead a dough from the ingredients of the shortcrust pastry with cool hands or with the dough hook of the mixer. Then chill for 30 minutes (refrigerator).
Roll out the dough in a greased and floured springform pan and sprinkle with a little semolina or breadcrumbs (to prevent soaking).
Wash and peel the rhubarb, cut into short pieces and cover the base with them. Sprinkle the rhubarb with a little sugar.
For the topping, first beat the egg whites and sugar until stiff, then stir in the egg yolks, hazelnuts, semolina and sour cream (or cream or canned milk - depending on what`s available).
Distribute the icing evenly over the rhubarb.
Bake for at least 40 minutes at 175 ° C hot air or just under 200 ° C top and bottom heat (bottom rail). The cast shouldn`t get too dark. Therefore reduce the temperature towards the end if it gets too dark.
Tip: It tastes just as good with red träuble (currants) instead of rhubarb. I haven`t tried gooseberries yet, but it should also work well in terms of taste.
