In a large mixing bowl, combine cooked pumpkin, finely chopped onion, minced ham, chopped parsley, grated nutmeg, grated lemon rind, salt, pepper, and 2 beaten eggs.

Mix all ingredients together until well combined.

Form the mixture into round patties.

Coat the patties with flour.

Lightly beat the third egg in a separate bowl.

Dip the flour-coated patties into the beaten egg.

Coat the egg-dipped patties with breadcrumbs.

Melt butter in a large frying pan over medium heat.

Fry the patties in the melted butter until lightly browned on both sides, approximately 5-7 minutes per side.

Serve hot.
