Take one pound cold boiled fish left over from the day previous, or boil
fresh fish and let cool, then skin, bone and flake. If fresh fish is
used, mix two tablespoons of vinegar, a pinch of salt and pepper with
the fish. Make a mayonnaise dressing (French mayonnaise preferred), and
mix half with the fish, leaving other half to spread over top of salad,
after it is put in bowl. Serve either with or without lettuce leaves.
