Hotaruika (Firefly Squid) — First Arrival of the Season
Two unusual items this week, both frozen to comply with FDA parasite regulations for wild-caught seafood: Hotaruika (蛍烏賊, Firefly Squid) from Toyama Prefecture and Madai (真鯛, Sea Bream) from Hyogo Prefecture.
Hotaruika — firefly squid — are tiny bioluminescent squid harvested from Toyama Bay on Japan's Sea of Japan coast. They measure only a few centimeters each, and the entire animal is eaten whole. The flavor is intensely savory and slightly sweet, with a richness that belies their small size. In Japan, the height of Hotaruika season is March through May, when the squid rise to the surface of Toyama Bay in enormous numbers to spawn — a spectacle visible from the shore. An autumn appearance like this one is less common.
Hotaruika is available in 3.5 oz packs at $16. Madai (Sea Bream) fillet is priced at $3.00 per ounce at the storefront.
How to Prepare Hotaruika — Beyond Sashimi
Most people encounter Hotaruika as sashimi or as lightly boiled and served with vinegared miso — both excellent. But the preparation that gets the most out of this ingredient, and the one that best suits the frozen-thawed product, is oil-based pasta.
The method: heat good olive oil in a wide pan over medium heat. Add whole Hotaruika and let them cook for two to three minutes — you'll notice the flavor of the squid transferring into the oil, which turns golden and fragrant. Add a little pasta cooking water and emulsify the sauce as you would an aglio e olio. Toss with spaghetti or linguine. The squid flavor permeates the entire dish in a way that doesn't happen with larger pieces of seafood.
A good Italian white wine alongside — an Etna Bianco if you can find one, or a mineral-driven Vermentino — completes the picture. The combination is not Japanese and not Italian; it belongs to the same category as the best things that happen when you stop worrying about authenticity.
Sea Bream (Madai) from Hyogo
Madai from Hyogo Prefecture is one of the most celebrated white fish in Japanese cuisine — clean, delicate, and versatile across preparations. The frozen-at-source process ensures parasite safety while preserving the texture well. At $3.00/oz at the storefront, it works as sashimi, as Kobujime (kelp-cured sashimi), or simply grilled with salt and a squeeze of Sudachi if Rice Market still has any left from last week.
Hotaruika pasta tip: Don't overcook the squid — two to three minutes in the oil is enough. Overcooking makes them rubbery and dulls the flavor transfer. The sauce should be the star; the squid are a flavoring agent as much as a protein.
