Course: Sauce
Keyword: Blender sauce, easy sauce, homemade sauce, sauce
A standing blender, food processor, or handheld immersion blender can all be used to make this sauce. The most important thing to look for is that the egg yolk and lemon juice sufficiently fill the bowl to reach the blades of the blender as they spin. This means that with blenders that have elevated blades or with many food processors, you may need to double the recipe. If using an immersion blender, use a narrow bowl or jar and run the immersion blender while pouring the warm butter down the side of the bowl.
