You may or may not know what hollandaise sauce is, but you’ve definitely eaten it: It’s that creamy yellow sauce that’s poured on top of eggs Benedict. While it sounds über fancy and complicated, hollandaise sauce is actually super easy to make with this blender hack. Instead of constantly whisking the egg yolks, melted butter, and lemon juice on the stove to fully emulsify the sauce, dust off your blender and swirl together all the ingredients for a couple of minutes. It’s totally foolproof, won’t leave your arm exhausted from a ton of whisking, and you don’t have to worry about the sauce breaking. Make a big batch of hollandaise for brunch parties and impress your friends by drizzling it on top of eggs, fried potatoes, or smearing it on a breakfast sandwich.
