Depending on the salad dressing that you’re making, the oil you choose can make a big difference. For a basic oil and vinegar dressing, I prefer the flavor of extra virgin olive oil. But, for a vinaigrette like this one, you want to choose a neutral oil to let the flavor of the fresh strawberries and basil shine through. I chose avocado oil because it has a very mild flavor. You could also use olive oil (not extra virgin) or grapeseed oil.
