Tamago no moto / egg yolk emulsion

This simple mixture of egg yolk and oil is often used to give fluffy texture and impart subtle richness. It also works as a moderate binder. For successful, creamy emulsification, add a small amount of oil to egg yolk at a time and whisk well. Otherwise, the two ingredients end up separating unhappily.

  • Amount of oil per egg yolk varies by individual cook and main ingredient (to which the emulsion is mixed), typically ranging from 2 tablespoons (30 cc) to 80 cc. 
  • Keeps for a few days to over a week, depending on the amount of oil mixed in.
