Steps
- Step 1
Melt the butter in a small saucepan over medium heat, or in a microwave-safe cup, until it is fully melted and very hot, almost bubbling. Keep it hot.
3 min
- 1 stick unsalted butter (8 tbsp)
- Step 2
Put the egg yolks, lemon juice, water, cayenne and salt in a blender. Blend on medium for about 20 seconds, until the yolks are pale and smooth.
1 min
- 3 large egg yolks
- 1 tbsp fresh lemon juice
- 1 tsp water
- 1/8 tsp cayenne pepper
- 1/2 tsp kosher salt
- Step 3
With the blender running on low, pour the hot butter in a very slow, thin stream through the hole in the lid — take a full 45 to 60 seconds. The sauce will thicken and turn glossy. Stop as you reach the milky white solids at the bottom of the pan and leave them behind.
1 min
- Step 4
Taste and adjust with a little more lemon juice or salt. If it is thicker than you like, blend in warm water 1 teaspoon at a time.

- Step 5
Serve right away, or scrape into a clean jar, press the lid on and refrigerate up to 5 days. It will set firm like soft butter when cold.
- Step 6
To re-warm a portion: spoon what you need into a small heatproof jar or bowl and set it in a bath of hot (not boiling) tap water, about 120°F, for 5 to 10 minutes, stirring often with a small whisk until it is loose, smooth and warm. Do not heat it over direct flame or it will break. If it looks separated, whisk in a teaspoon of warm water.
