Ingredients
Directions
Make the dressing
Mix the salt and pepper with the oil.
Slowly add the vinegar while stirring until the dressing becomes white and slightly thickened.
Use the dressing immediately or it will separate.
Marinate and serve
To marinate, cover meat or vegetables with the dressing and let stand for 2-3 hours.
Drain any unabsorbed dressing before serving.

What each ingredient does
- Oil
- Forms the fat base that carries the flavour and coats the food being marinated.
- Vinegar
- Adds acidity for sharpness and, stirred slowly into the oil, helps form a temporarily thickened emulsion.
The step that matters
Add the vinegar slowly while stirring. Oil and vinegar do not mix on their own. Slow addition with constant stirring breaks the oil into tiny droplets suspended in the vinegar, which gives the thickened, whitened texture. Without a stabilizer the droplets merge again and separate, so the dressing should be used promptly.
