Pure rendered duck fat is all the rage among accomplished chefs. Its delicate flavor is essential for French Confit preparations. A world class favorite is fried potatoes cooked in duck fat. All of our Pure Rendered Duck Fat is ANTIBIOTIC FREE and GLUTEN FREE with ABSOLUTELY NO ADDITIVES. Any good chef will tell you that used Duck Fat is far more valuable to them than a fresh pail of new Duck Fat. The reason is that flavor is retained in the Fat and thereby intensifies their next batch of cooking. Our Duck Fat is rendered under USDA inspection and has a Water Activity Level below 0.85, meaning that there is not enough moisture to support the growth of bacteria, yeasts, and mold. According to USDA standards, it is safe to ship our duck fat without refrigeration. However, refrigeration or freezing is highly recommended after you receive your Duck Fat.
