A marinade rather than a whole dish — this is the chicken you lay over a salad or a grain bowl. Butterflying is the step that makes or breaks it.
why it works
Virtually zero saturated fat, and the marinade is so intensely flavoured that you don't need a creamy dressing on whatever's underneath — a squeeze of lemon or a drizzle of balsamic is plenty. The acid in the sake and vinegar also genuinely tenderises the meat.
Lay the breasts flat on a board, put your hand flat on top, and slice horizontally through the middle almost all the way through, then open each one out like a book. Uniform thickness means it cooks twice as fast, absorbs the marinade deeper, and the thin end doesn't turn to cardboard waiting for the thick end.
Mix the soy, sake, rice vinegar, honey, ginger, garlic and chilli flakes in a bowl or zip-lock bag, and toss the butterflied chicken in. Fifteen to twenty minutes at room temperature, or up to 24 hours in the fridge.
Non-stick or griddle pan on medium-hot with a tiny spray of oil. Lift the chicken out, shaking off the excess but saving the leftover liquid in the bowl. Cook for 3–4 minutes on the first side until you get dark caramelised lines, then flip.
Pour the remaining marinade straight into the pan. It'll bubble and thicken into a sticky glaze — spoon it over the chicken as it finishes, another three minutes or so.
Out of the pan and rest for 3 minutes before slicing, then pour any remaining pan glaze over the sliced chicken.
