I made these "safe" frozen portions of butter from a regular block, so the butter is there for those special occasions, safely stored and not sitting in the butter dish, tempting you with it's tasty buttery goodness, all the time. That's why I call it "Safety Butter", and not "Individual Portions Of Butter".
The idea is you can just get one out when your diet allows it, and not worry about the rest of the block going rancid - so it's "safety butter" for that reason too.
Step 1: Cut out some paper
Step 2: Cut up the butter
I used a knife with a serrated edge for this, as it seems to be better for cutting butter with.
Step 3: Wrap the portions
Put the butter portions in your freezer container.
