When sprats are cheap, buy a good quantity, what in England you would
call a peck. Do not either wipe or wash them. Take four ounces of
saltpeter, a pound of bay salt, two pounds of common coarse salt, and
pound them well, then add a little cochineal to color it, pound and mix
very well. Take a stone jar and put in it a layer of the mixture and a
layer of the sprats, on each layer of fish adding three or four bay
leaves and a few whole pepper-corns. Fill up the jar and press it all
down very firmly. Cover with a stone cover, and let them stand for six
months before you use them.
