Escargots aux noix is a traditional dish originating from the southwestern parts of the country. The dish is usually made with a combination of snails, heavy cream, walnuts, white wine, butter, lemon juice, nutmeg, salt, pepper, and herbs such as parsley, chives, tarragon, and chervil.
The snails are tossed with wine and refrigerated. The butter is seasoned with the herbs, salt, pepper, nutmeg, and lemon juice before it's left to chill in the fridge. The butter is then melted in a skillet and mixed with walnuts, heavy cream, snails, and wine.
