Always use freshly squeezed citrus juices rather than bottled versions—freshly pressed juice delivers superior brightness, complexity, and prevents the metallic aftertaste that bottled juices can impart to your dressing.

The Dijon mustard acts as both an emulsifier and flavor bridge; start with 1 teaspoon and whisk it with vinegar before adding oils to help stabilize the dressing and prevent separation over time.

Grapefruit and lemon are more acidic than orange and lime—adjust their proportions based on your palate by starting with equal parts and increasing the sweeter citrus if the dressing tastes too sharp.

Whisk the citrus juices, vinegar, and mustard together for 30 seconds before slowly drizzling in the olive oil while continuously whisking—this creates a stable emulsion that clings to greens better than a separated dressing.

Add finely grated zest from one lemon and one orange to your dressing 10 minutes before serving to infuse subtle aromatic oils that amplify the citrus flavor without adding excessive liquid.
