From 1922:
The following has been found excellent:
Make a custard, allowing 5 eggs to the quart, ½ lb. sugar. Set to cool. Mash and strain 1 ½ lb. of strawberries, and add to the mixture, also half a pint of cream. Colour to a delicate shade with cochineal. You may substitute strawberry jam for the fresh fruit, but the flavour is not nearly so good. Any mixture to be frozen needs a liberal amount of sugar.
Another recipe is to heat, but not boil, a pint of milk with a pint of cream, and a ½ lb. of sugar. When cool add the crushed and strained strawberries, and freeze.
