Equipment. We prefer a bullet-style blender here, as it creates an exceptionally smooth dressing. This recipe also works with an immersion blender or full-size blender. Note: If your full-size blender is large, you may want to double this recipe so the blades have more herbs to "grab" onto, which will give you a smoother purée. 

This recipe is very forgiving. Adjust the amount of each ingredient to suit your tastes! 

Substitutions. Use fresh chives, cilantro, or parsley instead of basil (or use a mix of your favorite herbs). Swap the red wine vinegar for fresh lemon juice, apple cider vinegar, or white vinegar if you like. Add a clove of garlic or a few slices of shallot to this dressing for more of a bite. 

This dressing will solidify a bit in the fridge due to the olive oil - this is normal! Let it warm up on the counter for 5-10 minutes before using and stir vigorously to loosen it up again. You can also whisk in a splash of warm water to loosen it up.
