I don’t mind the separation, and I don’t mind the mixing. What I do mind is the spillage that results because the jar is too small. Mixing a full jar of peanut butter and not spilling some of the peanut oil over the side is impossible. A forever oily jar is a pain too. Surely it can’t cost that much to make the jar a tiny bit taller to aid in the mixing?
For many years now we have been buying natural peanut butter. The kind with just peanuts as the only ingredient. The kind that separates when left sitting for a while.
