How to Clarify Butter

Clarified butter gives you the rich flavor of butter without the smoking and burning that happens when milk solids hit high heat. French cooks call it beurre noisette when taken a step further, but plain clarified butter is your reliable partner for searing and sautéing.

Before you start

Use good butter and watch the heat

Start with more butter than you need since you'll lose about a quarter to milk solids and water. Keep the heat gentle — rushing will give you burnt bits instead of clean clarification.

Ingredients

The separation

Watch for three distinct layers

As butter melts, it separates into foam on top, golden butterfat in the middle, and white milk solids that sink to the bottom. The middle layer is what you want.

Step by step

  1. Cut butter into even pieces. This helps it melt uniformly without any pieces browning before others are melted.
  2. Melt butter over low heat. Place in heavy saucepan and keep heat gentle. The butter will melt, bubble quietly, then start to foam as water evaporates.
  3. Skim the white foam. Use a spoon to remove the foam that rises to the surface. This is coagulated milk proteins — you want it gone.
  4. Watch for the clear golden layer. Beneath the remaining thin foam, you'll see pure golden butterfat. White sediment settles on the bottom.
  5. Strain through cheesecloth. Line your strainer with cheesecloth and slowly pour the golden middle layer through, leaving the white sediment in the pan.
  6. Store in clean jar. Clarified butter keeps at room temperature for weeks or refrigerated for months.

Questions

How do I know when all the water has evaporated?
The bubbling will change from vigorous to gentle, then stop almost completely as the last water evaporates.
Can I clarify salted butter?
Yes, but the salt stays with the milk solids, so you'll lose most of the saltiness in the final product.
What's the smoking point of clarified butter?
Around 450°F compared to regular butter's 350°F, making it much better for high-heat cooking.
