POACHING
Filets of fish take particularly well to poaching. Any kind of fish may be poached, but the sorts with firm flesh, such as sea bass, striped bass, pompano, red snapper and Spanish mackerel are less likely to break when they are lifted from the pan. All the savory ingredients are put into the pan with the liquid in which the fillets are cooked. The fish has gains flavor and at the same time adds its flavor to the cooking liquid. This liquid is then enriched and thickened with cream, butter or cream sauce and served with the fish. Use just enough liquid barely to reach the top of the fillets. To insure even cooking of the fish, cut a circle of buttered paper the size of the pan. Punch a tiny hole in the center of the circle to allow steam to escape. Cover the fish with (his paper and then cover the pan lightly. Use a shallow pan large enough so that the fillets can be arranged side by side, in a single layer.

The fish is cooked when the flesh is no longer translucent, and will flake readily at the touch of a fork. The cooked fillets may be removed to a platter while the sauce is being prepared, or they may be left in the pan.
