- Why did the sauce separate?
- You added the oil too fast. Whisk vigorously again, or shake in a jar, and it will come back together.
- How long does it keep?
- In the fridge, in a sealed jar, it keeps for 1-2 weeks; in fact, flavours mature over time.
Spicy mustard & balsamic vinaigrette
This vinaigrette is a harmony of opposites: the deep, fruity sweetness of balsamic vinegar meets the sharp acidity of mustard and the fire of chilli. This isn't a cooked sauce, but an emulsion, where mustard (as an emulsifier) helps bind the oil and vinegar into a creamy, glossy dressing. A perfect choice for steak as a cold sauce, or the crowning glory of a rich salad.

Instructions
1
✓
Halve the chilli, scrape out seeds, then dice the flesh very finely. Crush the garlic to a paste.
Tip: The sauce texture is good if the solid pieces aren't distracting, so chop chilli and garlic as finely as possible.
2
✓
In a bowl, mix smooth the balsamic vinegar, mustard, honey, salt, pepper and crushed garlic.
Tip: It is important to mix water-based ingredients first, as salt and honey don't dissolve in oil [Solubility].
3
✓
Add the chilli to the mixture.
Tip: This allows the chilli heat to permeate the vinegar base.
4
✓
While whisking continuously and quickly, drizzle in the olive oil in a thin stream.
Tip: Oil must be added slowly so the mustard has time to 'wrap around' oil droplets, creating a stable emulsion.
5
✓
Taste, and if too acidic, add a little more honey. Let stand for 15 minutes before serving.
Tip: During resting, chilli heat and garlic aroma diffuse into the liquid.
