First split the kidneys in four pieces, trim off as carefully as
possible the sinews and fat that are inside, then cut in small pieces.
_Saute._--The quicker this is done the better the kidney. For a whole
one put about two ounces of butter in a frying-pan and set it on a very
sharp fire, toss it round so as to melt the butter as fast as possible,
but without allowing it to blacken; as soon as melted, turn the cut
kidney in, stir now and then with a wooden spoon for about three
minutes, then add a tablespoonful of flour, stir again the same as
before for about one minute, when add a gill of white wine and about one
of broth; stir again now and then till the kidney is rather underdone,
and serve immediately.
If the kidney is allowed to boil till perfectly done, it will very
seldom be tender.
It may be done with water instead of wine and broth; in that case, add a
few drops of lemon-juice just before serving it.
Prepare and serve it also as calf's-kidney, in every way as directed for
the same.
