Jon and I make our own peanut butter now.
We use peanuts that we need to shell, we sometimes shell other nuts as well like nuts from christmas nut bags.
We blend the nut with a little sugar and some butter, maybe a little milk depending on what consistency you want, we blend it all in the bullet. It's made in minutes and it tastes awesome.
We keep our homemade peanut butter in the fridge and it gets used up real quickly too!
We once made a batch of cookies out of our own homemade peanut butter, and the cookies were so tender and delicious, I wish I could give you one to try!
