The Foie Gras of the Sea

Ankimo (Monkfish Liver) stands as one of Japan's three great chinmi (rare delicacies), alongside karasumi (dried mullet roe) and konowata (sea cucumber intestines). Its rich, custard-like texture and deep umami flavor genuinely rival French foie gras — many chefs and gourmets consider it the superior product.

The preparation is an art — the massive liver of the Ankou (Monkfish) is carefully cleaned to remove all blood vessels, marinated briefly, rolled tight in bamboo mat, and steamed. The finished product is served chilled and thinly sliced, typically with ponzu, grated daikon, and finely sliced scallions. The pairing with cold sake is legendary.

Advance Intertrade sources both raw ankimo (for chefs who prefer to prepare their own) and pre-cooked steamed rolls (ready to slice and serve). Winter is the essential season when the liver reaches its maximum size and richness.

How It's Served

    Sake Pairing

    A legendary pairing with cold junmai or premium dry sake — the fat richness of ankimo cuts through the alcohol beautifully.

  • 🍞
