Having cleaned the fish, and cut off the fins, dredge them with
flour. Have ready some beaten yolk of egg, and in a separate dish
some grated bread crumbs. Dip each fish into the egg, and then
strew them with bread crumbs. Put some butter or fresh beef-dripping
into a frying-pan, and hold it over the fire till it is
boiling hot; then, (having skimmed it,) put in the fish and fry
them.
Prepare some melted butter with a spoonful of mushroom-catchup and
a spoonful of lemon-pickle stirred into it. Send it to table in a
sauce-boat to eat with the fish.
You may fry carp and flounders in the same manner.
