Blend on high for 30–45 seconds until the dressing is completely smooth, creamy, and emulsified. Scrape down the sides with a spatula and blend again briefly if any chunks remain.
Taste and adjust seasoning — add more lemon juice for brightness, more pepper for heat, or more nutritional yeast for depth.
2 medium lemons, 1-2 teaspoons freshly ground black pepper, 1-2 tablespoons nutritional yeast
Transfer to an airtight glass jar or container and refrigerate. Serve immediately or store in the refrigerator for up to 2 weeks.
Notes
Storage: Keep in an airtight container in the refrigerator for up to 2 weeks. Use a clean spoon each time to prevent spoilage.Make-Ahead: This dressing tastes even better after a few hours in the fridge as the flavours meld. Double the batch to have it ready all week.Substitutions: Swap red wine vinegar for white wine vinegar. Replace nutritional yeast with 1 tablespoon of white miso paste for extra umami depth.Freezing: Not recommended — the emulsion will break and the texture becomes grainy upon thawing.Pro Tip: Add ingredients to the blender in liquid-first order (lemon juice, vinegar, caper brine, then oil, then mayo and solids) to help the blade catch everything and emulsify faster.
