Prep Time: 10 minutes mins
Total Time: 10 minutes mins
- 10 tablespoons ( 1 1/4 stick) unsalted butter
- 1 egg, cold
- 1 egg yolk, cold
- 1 tablespoon freshly squeezed lemon juice
- 2-3 dashes hot sauce, optional
- 1/2 teaspoon whole grain mustard, optional
- salt and pepper
Melt the butter. Melt the butter in a small saucepan over medium heat. Swirl occasionally and don't let it boil. Once the melted butter is foamy and the foam is minimal and floating on top, pull it off the heat. Transfer to a heat-safe measuring cup for easier pouring.
Mix the ingredients in a mason jar. Find a mason jar or narrow heat-safe container that just fits the heat of your immersion blender with little room to spare. Add the egg, yolk, lemon juice, and hot sauce to the jar.
Blend the hollandaise. Place the head of the immersion blender into the jar and blend the eggs up, then slowly stream in the butter with the immersion blender running. You may need to move the head up and down to mix everything all the way. The sauce should be thick enough to coat a spoon, but still flow off. If it's too thick, add a teaspoon or two of warm water and blend until it's the desired consistency. Season to taste with salt and pepper and stir in the whole grain mustard, if desired.
Serve. Serve the blender hollandaise sauce right away. You can keep the mason jar warm in a bowl or pot of warm water for up to 1 hour. Stir regularly to keep a skin from forming.
