Akashiyaki

The exact origin of akashiyaki is unrecorded, but it is documented as an old Akashi snack tied to the local craft of akashidama, an imitation coral. From the late Edo period into the Taisho era, Akashi had a thriving trade in akashidama, made by binding saltpeter with egg white to imitate coral for hairpins and other ornaments; this craft is attributed to a late-Edo metalwork artisan, Edoya Iwakichi, who is said to have hit on the idea after egg white set in his pocket on a cold day. The white was used for the beads, leaving large amounts of yolk, and akashiyaki is widely held to have begun as a way to use that surplus egg together with the city's plentiful octopus. The modern yatai (street-stall) form is generally dated to the Taisho era and attributed to a vendor named Seitaro Mukai. Akashiyaki is also documented as the precursor of Osaka takoyaki: Endo Tomekichi of the stall Aizuya, who had been selling a flour-based snack called radio-yaki from 1933, switched its filling to octopus around 1935 on a customer's suggestion that he borrow from Akashi's tamagoyaki, and so created takoyaki.

Hot and barely holding together, an akashiyaki ball collapses softly the moment it leaves the mold, custardy and almost liquid at the center where the egg is only just set. The flavor is gently sweet and deeply eggy, with a clean savory backbone from the dashi soaked into the batter and a firm, slightly chewy nub of octopus at the core for contrast. Dipping it in the warm dashi loosens the surface further and floods each bite with broth and a scatter of mitsuba or scallion. A good one is fragile and almost molten inside; an overcooked one turns rubbery and dry and loses the trembling softness that is the whole point.

Akashiyaki sets soft because the batter is mostly egg, with only a small amount of light, low-protein starch (jinko, a wheat or wheat-rice starch) rather than the higher proportion of wheat flour used in takoyaki. With little gluten to form a firm network, the egg proteins coagulate into a tender, custard-like gel instead of a chewy crumb; the starch thickens the mix and, because it does not toughen on cooling, keeps the texture soft and yielding. The copper mold is the second key: copper's high thermal conductivity spreads heat fast and evenly across the wells, setting a thin skin on the outside while the interior is pulled from the heat before it can firm up, so the center stays barely cooked. Finally, the warm dashi dip rehydrates and loosens the egg surface and layers on glutamate umami; the kombu-and-katsuobushi broth combines glutamate from the kelp with inosinate from the dried bonito, a synergy that multiplies perceived savoriness far beyond either alone.
