I strongly recommend you to make your own. A freezer only costs l1s. 6d., and it will soon pay for itself. You will thus have better flavoured ices, and you will be sure not to be poisoned.
None of these recipes are, as you can easily see, very complicated. You will do well by avoiding any that are. Let your motto be
Dish up neatly, though not gaudily, and serve hot, very hot, and then you will be sure to please both eye and palate.
