Ingredients

  • 1 egg yolk*
  • 1/2 teaspoon fine salt
  • 1/2 teaspoon dry mustard
  • 2 pinches sugar
  • 2 teaspoons fresh squeezed lemon juice
  • 1 tablespoon white wine vinegar
  • 1 cup oil, safflower or corn

Method

  • In a glass bowl, whisk together egg yolk and dry ingredients. Combine lemon juice and vinegar in a separate bowl then thoroughly whisk half into the yolk mixture. Start whisking briskly, then start adding the oil a few drops at a time until the liquid seems to thicken and lighten a bit, (which means you've got an emulsion on your hands). Once you reach that point you can relax your arm a little (but just a little) and increase the oil flow to a constant (albeit thin) stream. Once half of the oil is in add the rest of the lemon juice mixture.
  • Continue whisking until all of the oil is incorporated. Leave at room temperature for 1 to 2 hours then refrigerate for up to 1 week.
  • FYI... Letting it sit out for an hour or two allows the acid in the vinegar & lemon juice to kill any bacteria from using the raw egg yolk.
