16 oz For those who prefer a crunch, still only one ingredient. INGREDIENTS: 100% Peanuts. Crazy Richard's Peanut Butter got it's start in the 1980s when Richard Marcus started making natural peanut butter in his kitchen. Friends called him "crazy" for focusing on health food at the time, leading to the name. Their products contain 100% US-grown peanuts (or single nuts) with no added salt, no added sugar, and no oils (except for specialized lines like Natural No Stir which use RSPO-certified sustainable palm oil).
