High praise for the Cuisinart 14-cup food processor. You can make great peanut butter with this Mercedes! Throw in the peanuts, maybe a touch of salt, 2 minutes later, peanut butter. If you buy organic peanuts, this method definitely includes a price break. One exception, keep this faster to separate homemade peanut butter in the refrigerator. If you prefer chunky style, throw in a handful of chopped peanuts after grinding the peanut butter.
