Top quality home made fish stock 100% natural ingredients - no \"extracts\" Superb base for a sauce We make this stock ourselves, always from the bones of let us say, superior fish. We sweat the characteristic vegetables (all chopped by hand freshly every time - we don\'t use \"extracts\") in olive oil. These are combined with the bone broth, a little wine, a few herbs and nothing else. After a gentle simmer, we strain it oh so carefully. Use this superb product as a cooking medium to elevate any fish onto a higher plane, or add vermouth, wine and/or cream to create a great sauce.
