About this cut
Wagyu Tan, particularly the 'Tan-moto' or root, is a rare delicacy prized for its unique structural contrast of buttery tenderness and a distinctive, springy snap. Unlike conventional beef tongue, the Wagyu variety features intricate intramuscular marbling that renders into a luxurious, fatty mouthfeel when exposed to high heat. It delivers a clean, concentrated beef profile with a sophisticated mineral finish, making it a cornerstone of high-end Japanese culinary tradition.
Taste-DNA
Located within the musculus linguae, the tongue is a highly active muscle; however, the posterior root portion contains significantly higher fat deposits and less connective tissue than the tip. This anatomical gradient dictates that the base is best suited for quick-sear applications, while the tip requires long-braising.
Preparation
Cooking Guide
Slice the root portion thinly (2-3mm) and grill over high-heat charcoal until the exterior achieves a deep Maillard reaction and the fat begins to sizzle. Aim for a medium doneness of 54-56°C to ensure the internal fat emulsifies while maintaining the signature textural 'pop.' Avoid overcooking, which can lead to a rubbery texture; instead, prioritize a rapid sear and a brief rest to allow juices to redistribute.

Portions per Person
Simple seasoning with high-quality sea salt and a touch of lemon juice highlights the Wagyu fat; pair with a crisp, high-acidity Chablis Premier Cru to cut through the richness.
