First stir the yoghurt until smooth and season with salt, pepper and the squeezed garlic. Now core the tomatoes and cut the pure pulp into small cubes. Then wash the basil, spin dry and finely chop.
Stir both ingredients into the seasoned yoghurt and let the dip steep for 1-2 hours.
Tip:
If you want to save calories, you can mix lean quark with 3.5% yoghurt 1: 1 instead of the Greek yoghurt, then the dip gets a slightly sour note.
If tomatoes and basil are exchanged for pitted and grated cucumber and dill, you get a simple but very tasty tzatziki.
