1 large egg
1 tablespoon freshly squeezed lemon juice (white wine vinegar can be substituted, if necessary)
1 tablespoon Dijon mustard
1 14 cups canola oil (see directions)
The oil you use is up to you, and you can use one oil or a combination of oils; try using just canola oil the first time you make this, but using 1 cup canola oil and 1/4 cup olive oil is nice, too. Also note that if you want a very thick mayonnaise, don't use one egg: use two egg yolks instead. Okay, note number three: according to the folks at Cuisinart, you can substitute 2 tbsp of Egg Beaters for the raw egg; you OMIT the lemon juice/vinegar when you do this; I have never done this myself, mind you, so I can't vouch for the taste of the results. Okay, let's make mayo. Into your food processor (fitted with the metal blade, with the food pusher left in), place the egg, lemon juice, mustard, and ONE TBSP of the oil. Process for one minute only. The food pusher in your food processor should have a small hole in its bottom; that is for recipes like this one. The next step is to place 1/4 cup of the oil in the food pusher; with the machine running, let this small amount of oil dribble through. Turn machine off and remove food pusher; then turn back on and SLOWLY pour remaining oil in. When done, taste; add salt and/or pepper if you wish. If you want a herby mayo, add 1/4 cup lightly packed fresh herbs (try parsley) in at the beginning, along with the egg. Keep mayo refrigerated. Note that this is REAL mayo, not the commercial stuff loaded with preservatives, and foods prepared with it shouldn't be left at room temperature too long.
