Sauces
Emulsification
Binding the unbindable
Coaxing fat and liquid into one silky, stable sauce: butter whisked into a pan sauce, olive oil streamed into a vinaigrette, pasta water married to cheese.
Why It Matters
Emulsions carry flavor across the entire palate at once. It is the difference between a sauce that clings to the food and one that pools, broken, at the bottom of the plate.
How to do it
- 1
Combine a fat and a water-based liquid.
- 2
Add an emulsifier like egg yolk or mustard.
- 3
Slowly whisk the fat into the base.
- 4
Use a steady stream to incorporate oil.
- 5
Continue whisking until smooth and stable.
Common mistakes
- ✕
Adding oil too fast breaks the sauce, so drizzle it in very slowly.
- ✕
Skipping the emulsifier causes separation, so include mustard or yolk.
- ✕
Using cold ingredients makes mixing difficult, so bring items to room temperature.
