In a bowl, mix the flour, sugar and butter (cut into small cubes) with hands to form a sandy dough. Pour into a pan/pot and brown over low heat, stirring constantly, then set aside.
Peel, core and cut the apples into large pieces. Cook them in the pan/pot over low heat with a knob of butter. Drizzle with lemon juice and sprinkle with cinnamon. Pour apples into the container(s) of your choice and top it with the dough. Take your spoon, no need to wait, it’s better hot!
