If you get tired of store-bought peanut butter and almond butter, why not make your own walnut butter? It's so easy! Mollie Katzen adds a little cinnamon and honey! It's best to refrigerate since there are no preservatives.
Spread nuts in one layer on a baking sheet. Toast until fragrant and lightly colored, about 10 minutes. Stir about halfway through the baking time.
Add nuts to a food processor, discarding any dried skin and dust. Add the salt and chop the nuts finely. With the motor running, drizzle in the oil. Whirl until the nuts are ground into butter, stopping to scrape down the sides two or three times.
