Whirl Butter Flavored Oil is a premium vegetable oil-based butter substitute that delivers rich, authentic butter flavor without the hassles of butter or margarine. This versatile 1-gallon (3.78L) jug adds delicious buttery taste to any dish and is superb in sauces, roux, and marinades.
Unlike conventional butter or margarine, Whirl maintains its robust butter flavor even in high heat applications such as grilling, sautéing, and pan frying, with proven high heat performance that won't scorch at high cooking temperatures. The product contains no water, ensuring 100% usability with no waste, and requires no refrigeration or clarification. This economical butter alternative is ideal for brushing on pizza crusts and breadsticks, as a replacement for butter or margarine in wing sauces, and for basting, broiling, and baking applications.
Whirl features artificial and natural butter flavoring and is certified Kosher by the Orthodox Union. Made in America and gluten-free, this butter-flavored oil provides authentic butter taste at up to half the cost of conventional butter and margarine.
