Step 1- Mix the Buttermilk Substitute
Combine the plant milk and apple cider vinegar in a small bowl and let it sit for a couple minutes while you gather the rest of your ingredients.
Step 2- Blend the Base
Place everything except the basil in a blender and process until smooth.
Step 3- Add the Basil
Add the basil leaves and pulse until they're broken up and the dressing turns a pale green color.
Step 4- Chill and Serve
Store in a glass jar or airtight container in the fridge. This dressing can be used immediately, but for best results, chill for at least an hour before serving.
