KITCHEN PRACTICE 2 — Make Awase Dashi and Compare Against Kombu Dashi
====================================================================

TASK
Make awase dashi and compare it directly against the kombu dashi from
Kitchen Practice 1. Identify specifically what the katsuobushi adds.

WALKTHROUGH

Step 1 — Make a fresh batch of kombu dashi.
Use the quick-heat method so you have hot dashi ready to add
katsuobushi to directly (the cold-steep method works too, but you'll
need to warm it before this next step).

Step 2 — Add the katsuobushi.
Bring the kombu dashi to a gentle simmer, add a loose handful (15-20g)
of katsuobushi, let it steep 30 seconds to 2 minutes, then strain
promptly. Save the spent kombu and katsuobushi - Kitchen Practice 3
uses them.

Step 3 — Taste both side by side, warm, plain.
Go back and forth between the kombu-only dashi and this new awase
dashi rather than tasting one, waiting, then tasting the other.

Step 4 — Note the specific difference.
Common observations: the awase dashi has a rounder, deeper, slightly
smoky or "toasted" quality the kombu dashi alone doesn't have; it
often tastes more like a "finished" stock, where kombu alone can taste
more like a background note waiting for something else.

--------------------------------------------------------------------
WHY THIS MATTERS
Kombu and katsuobushi carry different, real chemical sources of umami
(glutamate in kombu, inosinate in katsuobushi), and the two are known
to genuinely reinforce each other rather than just add up - awase
dashi tastes more than twice as savoury as either ingredient alone
would suggest. Tasting the direct comparison is the clearest way to
actually notice that combined effect rather than just being told about
it.
