I googled the difference between the both, and whilst tzatziki is often spoken off as a dip, apart from that the ingredients are pretty much the same.
1/2 a cucumber, grated
4tbsp greek yoghurt
1 small garlic clove, crushed
Large pinch of salt
Freshly ground black pepper
1 tbsp chopped mint, dry or fresh
Mix all the ingredients together and leave the develop for 30 minutes or more.
