What made my lemon vinaigrette taste flat: overblending or herbs?

[BrianHG]

Okay, so I’m trying to get better at making my own salad dressings instead of buying bottled ones. I made a pretty decent lemon vinaigrette last week, but this time I tried one with fresh herbs and it just tasted… flat and kind of muddy. I’m not sure if I over-blended it, or if the herbs weren’t fresh enough, or what happened. Has anyone else run into this when trying to make a really bright, herby dressing?

Bright herbs can be fragile in a salad dressing. A lemon vinaigrette often goes flat if you blend too hard and bruise the oil. Try pulsing briefly and letting the herbs steep a moment before tasting.

From a chemistry angle a bright salad dressing needs balance between acid fat and aroma. If you over blend the herbs you release bitter compounds and the perfume fades as the oil splits. Add the herbs after the emulsion is set or finish with a quick stir before serving. A dash of Dijon can help stabilize the emulsion and lift the herb notes.

I might be misreading but sometimes frozen herbs dull the brightness in a salad dressing and the texture feels muddy.

I doubt freshness is the only culprit. Sometimes a high acid lemon juice can feel sharp and you need a touch of sweetness or zest to balance. It might be the olive oil quality or the temperature that makes it feel flat.

Brightness can be more about staging the flavors than just dumping in herbs. Consider a citrusy base and a separate herb oil you drizzle in at the end for perfume rather than mixing all at once in the same bowl. That reframes the idea of a bright salad dressing as a two part approach.

On the craft side try different textures of herb chopped finely versus torn. You can grate lemon zest into the base instead of relying on juice alone. A splash of warm oil drizzle right before serving can wake the herbs in the salad dressing.

I like a simple method for salad dressing start with lemon juice salt and a touch of mustard whisk then slowly stream the oil while you whisk. Then fold in chopped herbs at the end and adjust with more lemon and salt. It keeps the aroma intact and avoids a muddy result.
