Separate eggs, chill egg whites. Mix egg yolk, 1 tablespoon sugar, milk, 1 pinch of salt and flour. Let the dough swell for about 45 minutes. Wash sultanas hot, dab dry. Mix with rum. Roast the almonds.
Wash the lemon, grate dry and peel some of the peel thinly. Squeeze the lemon. Peel apples, remove seeds and cut into pieces. Bring to the boil with wine, 3 tbsp. sugar, lemon juice and peel. Cover and cook over low heat for 8-10 minutes. Let the compote cool down. Remove lemon peel.
Beat egg whites until stiff. First stir sultanas into the dough, then fold in beaten egg white in 2 portions. Heat 1 teaspoon butter in a pan (approx. 18 cm Ø). Bake about 1⁄6 of the dough in it at medium heat for 3-4 minutes. Turn and bake for another 2 minutes. Pluck the pancakes into pieces with two spatulas. Dust with 1 tsp. icing sugar, add 1 tsp. butter and caramelise briefly while turning.
Warm up the finished rubbish. Bake the rest of the dough in 5 more portions in the same way. Serve the Kaiserschmarrn and compote. Sprinkle with almond flakes and dust with 1 teaspoon icing sugar.
A fine-sparkling South Tyrolean sparkling wine, e.g. from Chardonnay and Pinot Blanc, goes well with it.
