Notes
Store this raspberry walnut vinaigrette in the refrigerator for 5-7 days maximum. Olive oil can thicken when refrigerated, so you may need to stir it to recombine.
Tips & Variations
If you don't have balsamic vinegar on hand, you can swap it out for red wine vinegar or sherry vinegar.
I love my immersion blender because it's so quick and easy to clean, but you can also make this vinaigrette in a food processor or blender.
Swap out the olive oil with walnut oil for additional nuttiness! Avoid using vegetable oil if you can, since it lacks flavor and nutritional benefits.
Whole raspberries give this salad its fresh fruitiness, but you can also use raspberry preserves to get that delicious raspberry flavor. If you want your dressing to really pack a punch, try adding a few drops of raspberry juice concentrate!
For a little extra walnut flavor, toast your walnuts on a baking sheet at 350 for about 10 minutes. Let them cool before blending.
