Split into pieces a vanilla bean, and boil it in a very little milk till the flavour is well extracted; then strain it. Mix two table-spoonfuls of arrowroot powder, or the same quantity of fine powdered starch, with just sufficient cold milk to make it a thin paste; rubbing it till quite smooth. Mix together a pint of cream and a pint of rich milk; and afterwards stir in the preparation of arrow-root, and the milk in which the vanilla has been boiled. Beat it very hard, stir in half a pound of powdered loaf-sugar, beating it very hard again. Then strain it, and put it into a freezer placed in a tub that has a hole in the bottom to let out the water; and surround the freezer on all sides with ice broken finely, and mixed with coarse salt. Beat the cream hard for half an hour. Then let it rest; occasionally taking off the cover, and scraping down with a long spoon the cream that sticks to the sides. When it is well frozen, transfer it to a mould; surround it with fresh salt and ice, and then freeze it over again.
If you wish to flavour it with lemon instead of vanilla, take a large lump of the sugar before you powder it, and rub it on the outside of a large lemon till the yellow is all rubbed off upon the sugar. Then, when the sugar is all powdered, mix with it the juice of two large lemons.
For strawberry ice cream, mix with the powdered sugar the juice of a quart of ripe strawberries squeezed through a linen bag.
