Scalloped Fish Roe

Boil three large roes in water with, a very little vinegar for ten
minutes. Remove from the fire and plunge into cold water, wipe the
roe dry and break into bits without crushing. Have ready the yolks
of three hard-boiled eggs. Mash them into a cup of drawn butter with
salt, pepper, chopped parsley, a teaspoonful of anchovy paste, the
juice of half a lemon and a cup of bread crumbs. Mix very lightly with
the broken fish roe. Place in a baking dish, cover with bread crumbs
and bits of butter, and brown in the oven.
