For the avocado dip, halve, pit and peel the avocados and cut into small pieces in advance. Mix with yogurt and sour cream. While doing this, mash the avocado with a fork.
(You could also mash them, but if you do that with a fork, you’ll still have very small pieces of avocado inside.)
Squeeze the garlic into the mixture, as well as the juice of the lemon, add salt and pepper, and mix it all up again.
To make it look better in the dish, you can sprinkle the avocado dip a little paprika powder.
