1tablespoonlemon juicefrom 1/2 a lemon [2t white wine vinegar]
1cupvegetable or canola oil [1/2 canola1/2 olive oil]
Flavorings: to one half cup finished mayo add 1/4- 1/2 t of your favorite curry powder.
Place egg yolk, water, lemon juice or vinegar, dijon in the cup of an immersion blender (or a 1 quart take-out soup container). Pour oil on top and let settle for about 15 seconds. Use a lightly flavored oil unless you REALLY like the strong, spicy taste of olive oil.
Put the immersion blender all the way to the bottom of the cup and turn it on.
As you're blending, slowly move the blender up and tilt to the sides gently.
Continue blending and raising the stick blender.
It will magically come together, probably in less time than it's taking you to read this.
