Horseradish Mayonnaise
A trick to make mayonnaise is to drape a dishtowel over a small saucepan and set a metal bowl on it. This holds the bowl containing the mayonnaise in place and gives you the height you need for easy whisking. You can also use a hand mixer for this step, in which case, you will likely need to loosen up the mixture periodically with a few drops of warm water.
