Out of the numerous varieties of Croatian brudet, the one that hails from the Neretva region is considered unique since it usually employs eels and frogs, two traditional ingredients used in the area. It is said that every village in the region has a different recipe, but the basic version employs thoroughly cleaned pieces of eels and frogs that are sautéed alongside olive oil, onions, and garlic.

They are later braised in a combination of seafood stock, fresh tomatoes, chili peppers, and a touch of vinegar. Though tradition suggests the use of eels and frogs, the dish is commonly enriched with other fish varieties. Regardless of the differences, every version of brudet is always prepared in a traditional, heavy-bottomed pan and should never be stirred.
