Court bouillon (pronounced "Coor boo-yone") is a flavorful, aromatic liquid used for poaching fish and shellfish. The simplest court bouillon consists of nothing but salted water, and some traditional recipes call for a mixture of half salted water and half milk. This court bouillon recipe uses a mix of aromatics, spices, and acid, which will give the best results when poaching most kinds of fish and shellfish.
