This recipe for Iced Tea appeared in a newspaper in the US in 1887. Arthur Brooke founded PG Tips in the late 1800s and although iced tea was not a popular drink in England, he could have made this recipe.
For each person, allow one teaspoon of black tea, pour boiling water upon it and let it stand where it will “draw” for ten minutes; cool in a refrigerator, or on the bottom of the cellar. When ready to serve, sweeten, enrich with cream and pour upon bits of ice in a glass.
