Bring the milk with the salt to the boil in a saucepan rinsed with cold water. Sprinkle in the semolina and let it swell for 10 minutes over low heat while stirring. Mix the eggs with approx. 50 g butter, lemon juice and honey until frothy and mix with the semolina.
Grease a baking dish with butter, fill in part of the semolina, cover it with the nectarines and spread the rest of the semolina on top. Scatter the rest of the butter in flakes. Bake the casserole at preheated 200 ° C for about 1 hour until golden.
