Aomori Shamorock
Aomori Shamorock — two decades of research behind the cross
Said to be developed by Aomori's livestock experiment station over roughly two decades of research from a shamo and Barred Plymouth Rock cross; reportedly reared about 100 days for cockerels and 120 for hens, 50–60 days longer than a standard broiler.
- Origin: Aomori Gonohe
- About 540 km north of Tokyo
Lineage
What it's made of
Said to combine shamo's muscular bite with a moderate layer of fat from its Plymouth Rock side; the longer rearing period is credited with a well-judged springiness and depth of flavor, the two bloodlines said to come together in balance. Grilled, the fat stays light, said to leave shamo's springiness standing out to the last bite. It resists toughening once cold, said to work well across a range of dishes.
How it's made
Said to be developed by Aomori's livestock experiment station over roughly two decades of research from a shamo and Barred Plymouth Rock cross; reportedly reared about 100 days for cockerels and 120 for hens, 50–60 days longer than a standard broiler. That long research process is said to have involved repeated efforts to stabilize breeding. The roughly two decades of research reportedly involved repeated patient selection to stabilize breeding.
Why it took this shape
Aomori is known for its cool climate, long considered unfavorable ground for raising chickens. Spending some two decades on research reflects a persistence in chasing quality despite conditions stacked against it — pride in that persistence said to be carried in the name Shamorock itself. Its brand value is said to rest on the track record of producing a high-quality bird despite Aomori's harsh climate.
Dishes in the same style
- Aizu JidoriA lineage said to have been brought to Aizu by Heike clan refugees, saved from near-extinction and re-established through crossbreeding by Fukushima prefecture; reportedly fattened for 90 to 170 days.
- Amakusa DaioA large-bodied meat fowl once kept in Amakusa in the Meiji and Taisho eras, said to have died out in the early Showa period before Kumamoto prefecture spent roughly a decade recreating it; reportedly among the biggest jidori breeds, shipped at 120–150 days.
Ingredients and dishes from this land
Also from Aomori
- BekomochiColored strips of glutinous and non-glutinous rice-flour dough are bundled and steamed so each slice reveals a pattern — a Boys' Day treat from rice-poor Shimokita, its designs elaborated around Oma town.
- HittsumiHand-torn pieces of kneaded wheat dough are simmered in a chicken-and-soy broth with carrot and burdock — a dish from the old Nanbu domain spanning southeastern Aomori and northern Iwate, once a rice substitute in lean years.
- KakkeThin buckwheat dough is cut into triangles, simmered with daikon and tofu, and dipped in garlic miso — said to have begun when the Nanbu domain banned fine-cut soba, leaving people to eat the offcuts instead.
- Kujira JiruSalted whale blubber is parboiled to render off excess fat, then simmered in a big pot with daikon, carrot and potato — a New Year dish from around Hachinohe's old whaling grounds, said to deepen in flavor over several days.
- Mame ShitogiMashed boiled green soybeans are kneaded with rice flour and sugar into a log and sliced — a Nanbu-region sweet that stretched scarce rice with beans, once offered to the mountain and harvest gods.
- GapparamochiLeftover rice or rice flour is sweetened with brown sugar and black sesame, poured into a pan and pan-fried on both sides — a Tsugaru snack said to have started as a way to use up the dregs from making rice-starch glue.
