Bottling Butter

Asked February 13, 2013, 3:40 PM EST

I have seen articles lately about bottling butter. Once said to boil it and bottle as you would vegetables. One said to put the bottles in the oven, add the butter, let it melt, and then secure with a boiled flat and ring.

Are these methods safe for keeping butter and margarine?

Short answer - no
Long answer - butter is a dairy product which has a high concentration of fat. It is difficult to heat fat evenly (hot spots in pastries heated in a microwave is one example). Safely preserving food at home is dependent on heating food thoroughly and evenly. And since we can't be certain of heating fat evenly it is not a food we can home process.
Alternative: Freeze it! If it is in quarters, freeze as it. Double bag in freezer safe bags to avoid any moisture loss. Or cut into squares/pats, freeze single layer and then bag when frozen -instant individual servings
