Use low heat and avoid stirring the butter while clarifying it. This allows the milk solids to separate and settle without scorching.
Clarifying butter involves removing the water and milk solids, leaving behind pure butterfat. Burning or excessive browning occurs when the milk solids scorch. Here's a step-by-step guide to prevent this:
Use a heavy-bottomed saucepan: This helps distribute heat evenly and prevents hot spots that can burn the milk solids.
Cut the butter into small pieces: This ensures it melts evenly and quickly.
Melt the butter over low heat: Patience is key. Low heat prevents the milk solids from browning too quickly.
Avoid stirring: Stirring can disrupt the separation process and cause the milk solids to mix back into the butterfat.
Skim off the foam: As the butter melts, a foamy layer will form on top. This contains some of the milk solids. Skim it off gently with a spoon.
Watch carefully: Once the butter is fully melted, you'll see a clear, golden liquid (the clarified butter) and milk solids settled at the bottom of the pan. Be vigilant and remove from heat before the solids brown too much.
Carefully pour off the clarified butter: Gently pour the clear, golden liquid into a clean container, leaving the milk solids behind in the saucepan. You can also use a fine-mesh sieve lined with cheesecloth to strain the butter.
If you accidentally brown the milk solids slightly, don't discard the whole batch! You've essentially made brown butter (beurre noisette), which has a delicious nutty flavor. Just don't let it burn to a bitter, acrid state. Use it in recipes where that flavor profile is desired.
