Strawberry and Apple Jams have a forgotten history when it comes to tea not only in America but world wide. These Jams were commonly used (as well as honey) during post WWI as a sweetener , as sugar was costly and often rationed.  A teaspoon of jam would be added to the hot beverage. Adding a teaspoon of Jam to your tea certainly sounds more appealing than the artificially flavored ones available on the market these days.
