Boil the beef tongue for at least 3 hours. Remove from water, rinse, and allow to cool enough to handle.

Peel off the skin (for those of you who enjoyed Anatomy and Physiology, this part is awesome!!!), cut the meat into long strips, and set it aside.

Place a skillet over medium heat, then heat the sesame oil and add the garlic and ginger.

When the garlic has browned slightly, whisk in the lemon juice, vinegar, coconut aminos, salt, and pepper.

When the mixture comes to a simmer, add the arrowroot powder and stir until the sauce thickens slightly.

Add the tongue strips and stir to coat the meat with the sauce.
