Pour vinegar and agave into Vitamix and puree on high speed for 20 seconds until combined.
With motor running on medium or high, drizzle in olive oil to create an emulsion. Don’t worry, if you don’t get the emulsification, the almonds will thicken up your mixture.
Blend in 2 tablespoons of almonds, then check for thickness and texture.
If necessary, blend in another tablespoon of almonds, until thick and creamy.
