Leftover cooking is not only ecologically and financially smart, it can also produce food which tastes better than the original. "Lepuska" is a traditional Finnish bread made of leftover mashed potatos. It is eaten fresh from the oven with butter - incredibly good... This version is made with leftover mashed sweet potatos. I know this is a bold statement, but I dare say they're even tastier!
(10 small / 6 large lepuskas)
3 dl wheat flour 3 dl mashed sweet potato 1/2 teaspoon fleur de sel 1 egg
Preheat the oven to 200C.
Mix the egg, salt, and flour with cold mashed sweet potato.
Using a tablespoon, place small piles of dough on a baking tray covered with baking paper. Flatten the piles and bake for 20 minutes.
