More like it depends on whether the 1st ingredient is the same as (or at least compatible with?) the 2nd one - so long as they match, it’s fine!? :-P
Butter then peanut butter, but not peanut butter then jelly, cream cheese THEN stool sample, not the other way around, and so on.
Might depend how thoroughly the wipe (onto the bread) was, and how thickly lathered the PB afterwards? :-)
