This visually resembles a mille-crepe, with multiple layers of thinly sliced, tender juicy Satsuma Gyu 4% Miracle wagyu beef flank.
.
So named as it's the top 4% worldwide, with only 120 Tajima-Gyu / Japanese Black cows per year that have 80% or more fat, which is a miracle, 200g in total with prime marbling, coated in a crunchy panko breadcrumb crust and flash-fried.
.
It's then sandwiched within crisp soft toasted crustless shokupan / milk bread, and perfectly grilled.
.
Bite in and you get a robust smoky meaty savoury salty fatty sweet bready flavour.
