In the bowl of a food processor, add the garlic cloves and salt. Pulse for 1 minute or until the garlic is finely minced. Scrape down the sides of the food processor.
With the food processor running, slowly pour in 1 tablespoon of oil. Scrape down the sides of the bowl, and repeat alternating between adding 1-2 tablespoons of oil and lemon juice at a time until the mixture is well combined and creamy. This takes 10-12 minutes!
Add the sour cream, and pulse to combine.
Serve right away, or place in the fridge to chill.
Store in an airtight container in the fridge for up to 2 days.
