PREPARATION SUGGESTIONS
KETO RANCH DRESSING
Whisk 2–3 tbsp cultured buttermilk with mayonnaise, dill, chives, garlic powder, onion powder, and black pepper for a tangy, probiotic-rich dressing.
TENDERIZING MARINADE
Marinate chicken, pork, or beef 2–4 hours with cultured buttermilk, paprika, garlic, and herbs; lactic acid gently tenderizes without added carbs.
KETO BAKING INGREDIENT
Add 2–3 tbsp to almond- or coconut-flour batters for moisture and tang—great in savory biscuits or muffins.
CREAMY SOUP BASE
Stir 50–100 ml into pureed broccoli or cauliflower soup for creaminess and zip; warm gently to preserve cultures.
PROBIOTIC SMOOTHIE
Blend a small splash with avocado, spinach, MCT oil, and a few raspberries or strawberries for flavor while keeping carbs in check.
MASHED CAULIFLOWER ENHANCER
Fold 2–3 tbsp into mashed cauliflower with butter and herbs for a sour-cream-like tang.
