Peel the ripe avocado and mash it into a smooth pulp.

In a mixing bowl, combine the mashed avocado, sour cream, and milk.

Add the minced onion, mashed garlic pulp, minced fresh cilantro, and hot pepper sauce to the bowl.

Squeeze in the lemon juice.

Whisk all ingredients together until well combined and smooth.

Cover and let the mixture stand for at least one hour at room temperature to allow the flavors to meld.

Serve the avocado hot sauce with tortilla chips or as a topping for other dishes.
