Classic Vinaigrette (3:1 Oil to Acid)

3

Neutral or flavoured oil — Extra-virgin olive oil is classic; grapeseed, walnut, or hazelnut oil for variation

1

Vinegar or citrus juice — Red-wine, sherry, Champagne, or cider vinegar; lemon juice for brightness

0.25

Dijon mustard — Optional emulsifier — roughly 1 tsp per 4 tbsp total dressing; holds the break longer

to taste

Salt and black pepper — Season before tasting; salt must dissolve in the acid phase, not the oil

Whisk salt and pepper into the acid until dissolved. Add mustard if using and whisk to combine. Pour oil in a slow, steady stream while whisking vigorously to form a temporary emulsion. Alternatively, combine all ingredients in a sealed jar and shake. Taste and adjust acid or salt. The dressing will separate on standing — re-shake or re-whisk before serving.

• Always dissolve salt in the acid first — salt does not disperse in oil and will remain gritty.
• A 2:1 ratio (sharper) suits bitter greens like radicchio; 4:1 (richer) suits delicate butter lettuces.
• Room-temperature oil emulsifies more readily than cold oil straight from the fridge.
• Add a small clove of garlic (bruised, not crushed) to the dressing and remove before serving for subtle flavour without harshness.
• Mustard's lecithin and mucilage physically bridges oil and water droplets — even a small amount dramatically extends stability.
• For marinating meat, invert the ratio (1:1 or even 1:2 oil:acid) to maximise tenderising effect.

• Honey-Dijon Vinaigrette

  Add 1 tsp honey with the mustard; ratio softens to closer to 2.5:1 in perceived sharpness

• Walnut-Sherry Vinaigrette

  Replace oil with walnut oil and acid with aged sherry vinegar; classic with endive and Roquefort

• Lemon-Herb Vinaigrette

  Fresh lemon juice in place of vinegar, plus chopped tarragon or chives; goes with fish and asparagus

• Balsamic Reduction Vinaigrette

  Use aged balsamic at 1 part to 2.5 parts oil — balsamic is sweeter, so less acid is needed

• Miso Vinaigrette

  Japanese adaptation: white miso dissolved in rice vinegar acts as acid and emulsifier; ratio stays 3:1

• Pomegranate-Molasses Vinaigrette

  Middle Eastern; pomegranate molasses replaces half the vinegar, adding body and fruity tang

• Mayonnaise (Oil to Egg Yolk)

  A stable, permanent emulsion — vinaigrette made permanent by lecithin from the yolk

• Tahini Sauce (Tahini to Lemon to Water)

  Another oil-based sauce thinned with acid and water; similar flavour-balance logic

• Beurre Blanc (Butter to Reduction)

  Warm emulsified sauce built on the same acid-base that starts a vinaigrette
