02 / The lead

Aiko was trained on 60 years of Tsukiji market logs and the kaiseki notes of three Michelin-starred kitchens. Her dashi extraction times are not negotiable. She measures rice in grains, not cups.

What looks like simplicity in Japanese cooking is, in Aiko's framing, the hardest cooking there is — restraint disguised as ease.

04 / Backstory

The origin.

Aiko's training emphasized the structural ingredient: dashi. Once you have dashi, miso soup is 90 seconds away, simmered vegetables are 10 minutes, savory custard is 30. Her recipes teach the system, not the dishes.

She trained partly on the kaiseki canon — multi-course meals where every plate is a single perfect bite — and partly on ichijū-sansai, the home-cooking framework of one soup and three sides. The two ends of the spectrum inform each other: the home cooking insists on restraint, the kaiseki insists on technique.

She thinks the global "sushi" obsession is unfortunate. Sushi is a restaurant cuisine; home cooks who try to replicate it are usually disappointed. She'd rather teach you to make a clean dashi and a perfect bowl of rice.

Sushi is a restaurant. Cook rice well first.

10 / FAQ

About Aiko.

Do I need a rice cooker for Japanese food?

No. A heavy-bottomed pot with a tight lid works fine. The technique matters more than the gear.
