Recipe video above. The easy way to make this classic French Sauce! The end result is just as good as making it the classic way by hand -- which takes a good 15 minutes of whisking set over a double boiler and plenty of experience -- except it takes 90 seconds flat and it's foolproof.I prefer using a stick blender rather than normal blender because there's less waste / easier to scrape the sauce out.Use this sauce for Eggs Benedict, over aspargus, steak - it can fancy up anything! See in post for a list of ideas and notes for how to reheat leftovers easily.Makes about 1 1/4 cups, enough for 8 Eggs Benedict (ie 8 individual eggs). This sauce is rich, you don't need much per serve!
