No preservatives. Butter made in a small town in Tamil Nadu, stays fresh without fridge for weeks

Uthukuli butter, a GI-tagged delicacy from Tamil Nadu, boasts a divine taste and rich nutrition, lasting nearly a month without refrigeration. Its unique quality stems from local buffaloes' diet of drought-resistant grasses and seeds, yielding exceptionally high-fat milk. Traditionally hand-churned without preservatives, this butter's superior richness and creamy texture make it a culinary star, loved by chefs and home cooks alike for its versatility and deep flavor.
