This stuff needs to be kept in the refrigerator (like all natural nut butters made without preservatives) and should be consumed within three or four months. You can freeze it if you prefer, and it stores indefinitely in that case. (Don't "can" it however, because there's not enough acidity in nuts to make the process safe.)
Here's what you need:
Organic peanuts, about 2 cups
Organic coconut oil, melted, about 2 or 3 Tbs.
Raw, local honey, if you like
Sea salt, if you like
A container in which to store your peanut butter
Amounts are approximate- you'll want to adjust to your family's taste preferences
