It is a bacon pie/flan with a rye flour crust on the base and made with eggs, and in some villages contains high proportion of leeks or onions. It is popular as a quick snack in Kassel, especially on market days, sold at food stalls and bakeries. As with many regional specialties, every village and every baker has his own Speckkuchen recipe.
