Ingredients:

1 pint of Nut or Olive Oil.

2 raw yolks of Eggs.

1 tablespoonful of Vinegar.

1 saltspoonful of dry Mustard.

Salt and Pepper to taste.

How To Make:

Put the yolks of eggs into a dry basin, add the mustard, salt and pepper and a drop of oil; mix well with a wooden spoon, add the oil drop by drop very slowly, stirring well all the time. When it thickens add a drop or two of vinegar, then the oil and vinegar alternately, until all is used. Be very careful to add the oil very slowly at first or it will curdle.

It is best to use a basin with a handle, so that you get a firmer grip, and the hand does not touch the basin.
