Mine is equal measures of buttermilk and mayo, and then double of Greek yogurt, half the juice of one lemon, two tbsp of dried Parmesan, a teaspoon of dill, garlic granules, Maldon seat salt, onion powder, and cracked black pepper.
Makes that amazing ranch dressing you get on the side of fried shit in America and is great for pizza crusts but you can also make kids eat ANYTHING dipped in it.
I’ve watched my kids enthusiastically eat celery, radishes and green peppers which aren’t normally things they will eat raw.
