Classic Hollandaise Sauce
Ingredients
3 egg yolks
3 tablespoons lemon juice
½ cup melted butter
¼ teaspoon cayenne pepper
Pinch of salt
Directions
Prepare the double boiler: Fill a saucepan with about an inch of water and bring to a gentle simmer over medium heat.
Whisk the base: In a heatproof glass bowl that fits snugly over the pan, whisk together the egg yolks and lemon juice for 1–2 minutes until slightly thickened and emulsified.
Set over the simmering water: Place the bowl over the saucepan, ensuring the bottom doesn’t touch the water. Stir constantly as the mixture gently warms.
Add butter slowly: Gradually whisk in the melted butter, a few tablespoons at a time, allowing each addition to incorporate before adding more. Keep the temperature around 120°F to prevent curdling—remove the bowl occasionally if it gets too hot.
Season: Once thick, smooth, and glossy, stir in a pinch of salt and the cayenne pepper.
Serve immediately, or keep warm covered with foil.
If the sauce sits and begins to thicken too much, whisk in 1 tablespoon of boiling water to reconstitute before serving.
