To every quart of cream, allow two ounces of shelled sweet almonds, and two ounces of shelled bitter almonds. Blanch the almonds in scalding water, and then throw them into cold water; afterwards, put them, one at a time, (bitter and sweet alternately,) into a marble mortar, and pound them to a fine, smooth paste, moistening them with a little cream as you proceed. When the almonds are all done, stir them gradually into the cream you intend to freeze. Set it over a fire, and continue to boil it five minutes after it has come to a boil. Then strain it into a freezer, and while it is warm stir in gradually sufficient powdered loaf-sugar to make it very sweet, allowing three-quarters of a pound to every quart of cream. Freeze it in the usual manner.
To each quart of cream, allow three ounces of shelled bitter-almonds, and no sweet ones. Blanch them and break them up slightly. Put them into a porcelain sauce-pan, and pour on water, allowing half a pint of water to each ounce of almonds. Boil them long and slowly, till the water is highly-flavoured, and so reduced in quantity that it barely covers the almonds. Then strain it off; and when cool, stir the almond water into the cream, adding sugar by degrees; allowing three-quarters of a pound to every quart of cream. Put the mixture into a freezer, and proceed as usual.
