[Kochi Prefecture Shimanto City] Must-try ingredients in Shimanto City! [Part 1] Shimanto City offers so many recommended ingredients that it’s impossible to pick just one. Everything harvested from its rich nature is delicious. You can enjoy the river’s bounty, the sea’s offerings, and the mountains’ and countryside’s produce—experiencing Shimanto’s food culture and local cuisine. ○ River bounty from the Shimanto River: “Wild Eel” ・How to tell wild eel apart One way to distinguish wild eel from farmed eel is by the color of the belly. Wild eels spend long lives living on riverbeds and in holes in natural environments. When they feed or escape predators, they often rub their bellies against the river bottom, which can make the belly appear yellow. Because they get plenty of exercise, wild eels are muscular and have a firm texture with a clean, light fat and a concentrated eel flavor. Their girth is often larger than that of farmed eel. ・Delicious ways to enjoy wild eel Thick wild eel grilled over charcoal develops a fragrant, crisp skin and a springy, meaty texture. Popular preparations include kabayaki with sauce and shiroyaki seasoned simply with salt. The liver is used in clear soups, and the bones can be deep-fried. ・Eel fishing Shimanto River’s wild eel are caught by traditional methods such as ishiguro fishing and korobashi fishing, making them a valued local brand ingredient. Wild eel have become scarce in recent years, making them precious. The wild eel season runs from April to September. ・Glass-eel fishing Glass eels, the juvenile eels caught near the Shimanto River, are used for aquaculture. Nighttime glass-eel fishing in winter, lit by attracting lights, creates a magical scene. ○ Farmed eel with a near-wild taste ・How to tell farmed eel apart Farmed eel grow in environments without predators and eat steadily, so their bellies are white and their flesh is tender. They rarely move vigorously or rub against the riverbed, so they grow cleanly. With less exercise than wild eel, farmed eel often carry richer fat. ・Farming Eel farmed in Shimanto approaches the qualities of wild eel, offering resilient skin and firm, meaty thick flesh with a satisfying chew. The fat provides a light, savory richness. ○ A gift from the Shimanto River: “Wild Sweetfish (Ayu)” ・Two names for ayu Ayu often die after about one year and are called “year fish.” Because they feed mainly on riverbed algae, they have a pleasant aroma and are also known as “fragrant fish.” The taste of ayu varies with the river they grow up in. Wild ayu raised in clear rivers and fed high-quality algae are said to have a scent reminiscent of watermelon or cucumber; the wild ayu of the Shimanto River have a rich river fragrance worthy of the name “fragrant fish.” ・Wild ayu Because they scrape algae off stones with their teeth, ayu have developed front teeth and a pointed mouth. They take on a yellowish hue, a moist texture, and a firm belly. ・Delicious ways to enjoy ayu Salt-grilled ayu, which highlights the ingredient, is a classic preparation. Removing the tail, holding the head, and pulling out the bones makes it easy to eat neatly. The post-spawning “ochi-ayu” in December–January, when fat has dropped, is locally enjoyed as a light salt simmer. Other preparations include kanroni (sweet-simmered whole fish) that soften head and bones, and uruka, a salted-fermented ayu innards condiment—among many local ways to eat ayu. ・Ayu fishing Shimanto River still preserves traditional fishing methods such as tomogake (friend-hook) fishing, net fishing, and hiburi (torch) fishing. The wild ayu seasons are June to October 15 and December to January. ○ Springy texture: Shimanto River shrimp Three species of river shrimp inhabit the Shimanto River: tenaga shrimp, hirate (Yamato) tenaga shrimp, and southern tenaga shrimp. Males are notable for claws that can exceed their body length. ・Delicious ways to enjoy river shrimp River shrimp around 3–10 cm long are delicious deep-fried or salt-grilled and eaten whole with the shell for a toasty flavor. Locally, shrimp dashi is used to cook with cucumber or added to somen noodles. ・River shrimp fishing Shimanto River shrimp are caught using traditional methods like korobashi fishing and shibazuke fishing. With prior reservation, visitors can try easy shrimp-fishing experiences. The natural river shrimp season is May to August. ○ Shimanto River crab: Tsugani (Mokuzugani) Tsugani (also called mokuzugani) move downstream in late summer to early autumn to spawn. Although their edible meat is limited, their rich miso (crab paste) is exquisite. ・Delicious ways to enjoy tsugani Tsugani are enjoyed in dishes like tsugani soup, salted boiling, tsugani rice, and local specialties such as gane miso, celebrated as an autumn delicacy. ・Tsugani fishing Fishing methods include crab-basket fishing, where baited baskets are submerged and lifted the next morning, and flow-trap fishing that sets baskets along tsugani migration routes. The natural tsugani season runs from August to October. ○ Local snack: Shimanto gori Gori is a general name for freshwater gobies; in Shimanto City it mainly refers to juvenile gobies such as numachichibu. ・Delicious ways to enjoy gori Gori are deep-fried, simmered in sweet soy-based tsukudani, or locally cooked with finely chopped dried daikon wrapped in egg and served over rice as gori don. ・Gori fishing Fishing begins in March as the river warms and spring approaches. The main method uses the gobies’ habit of moving along the riverbed—nobori-otoshi ue fishing. Another local technique, gara-hiki fishing, has pairs pull a rope with shells attached from upstream to downstream; the clattering shells scare the gobies into traps. The natural gori season is March to May. ○ Fragrant green seaweed: aonori (sujiaonori) ・Delicious ways to enjoy aonori Aonori is dried into powder for use in many dishes and is also used in confections to take advantage of its aroma. ・Harvesting aonori The Shimanto River is one of the country’s leading producers of natural sujiaonori. In winter, you can see people scrape the seaweed that grows on estuarine stones with comb-like tools and sun-dry it. Aonori’s prime season is December to May. ・Delicious ways to enjoy aosa nori Aosa nori grown in the Shimanto River is highly fragrant and very tender. It serves as a base for nori tsukudani, is used for tempura, and is added to soups. ・Harvesting aosa nori From winter through spring, aosa nori cultivated on hibinetsu nets in the estuarine area near the Shimanto River mouth is harvested. The prime season for aosa nori is February to May.
