This is an especially good way to use up slightly over-ripe fruit or the fruit remainders that sometimes get left behind after making a recipe. Over-ripe fruit will mash more easily and its sweetness gets cut by the acid in the vinaigrette.
All we do is puree a half cup or so of fruit in our food processor along with the acid (usually lemon juice or vinegar). Then we stream in the olive oil with the blender still running to form an emulsion. This will give us a creamy, slightly-thickened vinaigrette. Yum!
Give it a try the next time you have salad!
