What the actual peanuts costs, filler stripped out
Three smooth peanut butters on the same shelf, judged on the one number the label buries: how much roasted peanut went in per 100g, the rest being oil, sugar and salt. The Sainsbury's own jar matches premium Whole Earth on peanut content at 96% but costs a third as much per pound of peanut, so it gives the most real peanut for your money. Whole Earth is the dearest per pound of peanut despite its no-added-sugar recipe, and Skippy has the least peanut at 91%.
Ranked by cost per 100g of actual peanuts — shelf price with filler stripped. Sources on each pack's own page.
