Ways of Cooking Fish

To Cook Fish in Boiling Water. Small cod, haddock, or cusk are cooked whole in enough boiling water to cover, to which is added salt and lemon juice or vinegar. Salt gives flavor; lemon juice or vinegar keeps the flesh white. A long fish-kettle containing a rack on which to place fish is useful but rather expensive. In place of fish-kettle, if the fish is not too large to be coiled in it, a frying-basket may be used placed in any kettle.
