Yakitori Hatsu (ハツ, chicken heart skewers)

Chicken heart makes people pause. The name does the frightening work; the cooking is plain. Hatsu is one of yakitori's cleanest skewers, lean and firm, more like dark meat tightened by exercise than the heavy offal some cooks imagine.

The detail that decides it happens before the fire. There is no calendar shun to rescue you here. Freshness is the season. Buy hearts that are deep red, glossy, and clean-smelling, then press out the dark clots and trim the pale tubes while keeping each heart whole. Leave those clots in and the skewer tastes metallic. Take them out and there's nothing strange left, only a clean piece of bird ready for salt.

After that, it is hot coals and timing. Salt gives the heart nowhere to hide, which is why I like it first; tare is equally at home if you brush it on late, after the outside has set, so the sugar glosses instead of burning. Hatsu belongs to yakitori's true grammar: one part of the chicken, one method, one skewer, served while the bite is still springy. The method, not the menu. That is the real doorway.
