Sauce Tartare ( a Cold Sauce ).
To a scant half pint of Mayonnaise sauce (made with the mustard added) mix in two table-spoonfuls of capers, one small shallot (quarter of a rather small onion, a poor substitute), two gerkins (or two ounces of cucumber pickle), and one table-spoonful of parsley, all chopped very fine. This sauce will keep a long time, and is delicious for fried fish, fried oysters, boiled cod-fish, boiled tongue, or as dressing for a salad.
By making the following simple sauce, one can produce several by a little variation.
