Be the first to Write a Review Dry aging is the secret to the rich, meaty flavor and buttery texture of these bone-in fillet steaks from Strassburger, a 150-year-old family-owned New York butcher that supplies some of the country’s top steakhouses and restaurants. The USDA Prime meat is expertly dry aged for three weeks at Strassburger’s onsite facility, a process that concentrates natural flavors and tenderizes the meat. The beautifully marbled steaks are delicious grilled or broiled.
