Makes 1 pound
1 pound of grass-fed butter (Kerrygold is a good brand)
Instructions
1. Melt the butter in a saucepan on low heat
2. Skim the milk solids (casein) that rise to the top in a foamy mixture
3. Strain the remaining butter through cheesecloth, into a glass container
Note: If you allow the butter to cook longer, the milk solids will turn brown and fall to the bottom. You can then strain the butter through cheesecloth. This is called ghee.
