Heat Control
Aromatics and Volatiles
Aroma molecules leave the pot fast. When you add them decides how much the eater smells.
Core Concept
Aroma comes from light molecules. Heat pushes them into the air. Garlic in hot oil at the start builds a deep base. The same garlic at the end gives a sharp top note.
Did You Know?
Japanese cooks add mitsuba and yuzu peel after the heat is off. The pot holds that smell for about one minute. That minute is the point of the dish.
Early or late, not both
Early aromatics melt into the dish and disappear as a smell. Late aromatics sit on top and hit the nose first. Pick one job for each ingredient.
A simple rule
Hard aromatics go in early. Soft green ones go in last. Ginger and garlic early. Scallion and herbs at the end.
Ryota says:
I add half the scallion at the start and half at the end. The pot gets depth and the bowl gets smell.
