Lemon-Mustard Vinaigrette - The Simplest and Best Salad Dressing - Recipe

Salad greens with lemon-mustard vinaigrette

I've never understood why people buy salad dressing, when an infinitely more delicious, fresher, healthier homemade vinaigrette is only 30 seconds away.

I make variations of vinaigrette all the time, but today I want to share with you my absolute favorite, the one I return to at least once a week. I use lemon juice instead of vinegar, and a good amount of Dijon mustard. The result is bracing, fresh and citrusy.

The traditional ratio for vinaigrette is 3 parts oil to 1 part vinegar. Depending on the intensity of your vinegar, this tends to produce a rather subdued dressing. Especially with lemon juice, I tend to prefer something around a 2:1 ratio. That is what I've specified in the recipe below, but you should always taste it and adjust to your preferences, the salad being dressed, and what you will serve it with.

Meyer lemons will give you an even better flavor than the grocery-store standard Eurekas, and of course you should use a tasty extra-virgin olive oil.

There are two advantages to adding a significant amount of mustard to a vinaigrette. The first is obvious: it tastes good. The second is that it acts as an emulsifier, keeping the oil suspended in the vinegar. When made this way, you can get away with combining all of the ingredients in a jar with a tight fitting lid and simply shaking well. It isn't necessary to drizzle in the oil while whisking in the traditional fashion, nor do you need a blender.

Salad dressings need to be highly seasoned with salt. Your salad will be lightly dressed, so if there isn't enough salt to make the straight dressing taste pretty strong, it will be underseasoned when applied to the greens.

You can feel free to add additional flavorings to this dressing. It will happily accept any finely minced fresh or dried herb, garlic, shallots, citrus zest or spices.

One last thought: this dressing is delicious on a big salad with lots of ingredients. But don't forget the joy of a simple salad of only lettuces, especially if they are fresh from the garden. You can grow (or find at a farmer's market) varieties that are far too delicate to be carried in a normal grocery store. The texture and flavor of these greens is incomparable. Treat them right by washing gently, drying thoroughly, and dressing at the very last moment. They will wilt within a very few minutes after meeting their vinaigrette.
