Though not technically a Mother Sauce, mayonnaise is the foundation for many sauces, dips, and dressings. Mastering a homemade mayonnaise will give you better control over flavor, and the slightly tangier flavor will make you a homemade mayonnaise convert.
1cup(or more if needed) neutral flavored oil like refined avocado or canola
1teaspoonsalt, plus more to taste
Instructions
In the bowl of a blender or food processor, add the egg, salt, and lemon juice (or vinegar).
Turn your blender or food processor to a medium-high speed and start incorporating your oil in a slow and steady stream that is slightly more than a drizzle.
Continue slowly adding the oil until it is completely combined and the homemade mayonnaise is thick and holds it's shape.
Notes
If your homemade mayonnaise is too thin, continue adding extra oil until it reaches your desired consistency. If it is too thick, add additional vinegar or lemon juice to thin it out.
