Drawn butter

Drawn butter is melted butter,[1][2] often served as a sauce for steamed seafood.

[4] When it is served with seafood, diners often add lemon juice to it.

In the 18th century, a small amount of flour and water or milk was often added to melted butter to thicken it and prevent it from separating.

Later in the 19th century, increasing amounts of flour and water were used.

[2] These sauces may themselves be named simply "melted butter", "drawn butter", or "drawn butter sauce", and flavored with vinegar, salt, pepper, capers, watercress, and so on.
