One assumption that I’m going to make about the French is that they’re not afraid to make things au pif, or “by the nose”.
I don’t know if a precise recipe for sauce vinaigrette actually exists. But if there is, I bet few people follow it very closely. And Romain is no different from his compatriots when it comes to recipes, and rules.
They are both for other people—and don’t apply to him.
Vinaigrette is just one of those things. It’s a few simple ingredients which come together so well, when done right. Anyone can make it: you just pour, stir, marinate, then taste until it’s just right. But the salad dressings in France always taste better to me than elsewhere. So thought I’d follow Romain when he made a true vinaigrette. He was surprised at the idea of measuring anything, so I follow him through the steps, taking a few notes along with way (see Recipe, at the end) and along the way, I learned two French secrets for a great salad dressing.
One is that you must use good Dijon mustard.
