This pack
Three jars of strawberry jam on the same shelf, judged on the one number the label buries: how much fruit went in per 100g of jam, the rest being sugar. The Sainsbury's jar has the most fruit at 41%, but the budget Stamford Street jar matches big-brand Hartley's on fruit (35%) at a fraction of the price, so it gives the most real fruit for your money. Hartley's is by far the dearest per pound of fruit.
Ranked by cost per 100g of actual fruit — shelf price with filler stripped. Sources on each pack's own page.
