HOW TO ENJOY IT ON KETO
- Moderate carbs—best as an ingredient, not a beverage
- A tablespoon or two adds big flavor with limited carbs
- Fermented dairy provides tang without added sugar
- Boosts flavor so you can skip higher-carb thickeners
- Traditional (churned) versions can be richer; still watch portions
- Ideal for marinades and dressings where small amounts suffice
PREPARATION SUGGESTIONS
KETO FRIED CHICKEN MARINADE
Marinate chicken 2–4 hours with buttermilk, garlic, and herbs; bread with almond-flour or crushed pork-rinds before frying in tallow, lard, or avocado-oil.
CREAMY SALAD DRESSING
Whisk 2 tbsp buttermilk with mayonnaise, herbs, lemon, and spices for a tangy ranch-style dressing.
KETO BAKING INGREDIENT
Use 1–2 tbsp in almond-flour biscuits or breads for moisture and tang; account for carbs.
MARINADE FOR FISH
Combine with lemon, garlic, and dill; marinate cod or halibut briefly before baking or pan-searing.
CREAMY VEGETABLE DISH
Stir 2–3 tbsp into sautéed spinach or broccoli with butter for a lightly tangy finish.
SPICE MIX BASE
Blend with spices for a low-liquid marinade on beef, lamb, or pork; the acidity tenderizes.
