3 C heavy cream
1/3 C sour cream
Combine ingredients in a stainless steel bowl. Cover with plastic wrap. Cut vents into the wrap. Leave out on the counter for 24 hours until thickened. It can thicken quicker. Overnight can work. It just depends on the temperature and biology in your kitchen. Once it has thickened, cover and place in the refrigerator. Wonderful for enriching soups, dressings, dessert toppings etc…Flavor with fresh dill, citrus, honey. Be creative.
