Steak ’n Shake bringing back grass‑fed beef and beef‑tallow fries is honestly a power move — that’s the kind of throwback flavor people have been missing. Beef tallow gives fries that deep, rich, almost “fair‑food” crisp that vegetable oils just can’t match. And grass‑fed beef has a cleaner, beefier taste that stands out even in a simple smashburger. Way to go!!!!!
