Crab Sauce. (Birk Hall.)
When you cannot obtain lobster for sauce.
2 tablespoonfuls of flour mixed well with very little cold water at all, lest it should be lumpy; you can use 1 pint of water in all. Let it boil for about 5 minutes, then pass it through a tammy cloth.
Mix with it about 3 ozs. of butter, taking great care it does not boil.
Take a boiled crab (see Appendix, regarding boiling crabs), and mince very finely the whole of the crab's meat, both hard parts and soft; add it the melted butter with a teaspoonful of essence of shrimps, some seasoning and ¼ pint of cream.
Let all warm through and mix, but not boil. Serve in a sauce-boat.
