Sweet Shrimp (Amberi): The Sweet Star on the Sushi Counter
Sweet shrimp (Japanese: Amberi, scientific name Pandalus borealis, English name Northern Shrimp), is a naturally wild shrimp species caught in deep cold waters of Japan's northern cold sea areas such as Hokkaido and the Hokuriku region (Ishikawa Prefecture). The name "sweet shrimp" perfectly encapsulates its defining characteristic — the rich natural sweetness derived from high levels of trehalose and glycine and other amino acids in the shrimp meat, requiring no seasoning whatsoever to shine.
Core characteristics of sweet shrimp: Outstanding sweetness — among all common raw-eating shrimp, sweet shrimp's natural sweetness is the most direct and pure; Tender texture — the shrimp meat is almost semi-liquid, melting on the palate; Appealing appearance — orange-pink body with translucent head, visually highly attractive; Precious roe — the emerald green shrimp eggs on the female's abdomen are the essence of the ingredient, bursting with fresh sweetness; Affordable price — compared to Botan shrimp, sweet shrimp is more affordable, serving as standard inventory for high-end to mid-high-end sushi bars.
Sweet Shrimp Origin Analysis
Hokkaido (Highest Grade): Otaru Fishing Port (Hokkaido sweet shrimp distribution center, stable quality, year-round supply); Yoichi coastal area (larger shrimp, more pronounced sweetness, favored by sushi professionals); Mashike coastal area (winter November to March is the peak quality season).
Ishikawa Prefecture (Hokuriku): Famous sweet shrimp production area around Kanazawa City, water temperature slightly higher than Hokkaido, sweetness differs slightly (more umami-forward), seasonal supply, peak season is autumn and winter.
Imported Sweet Shrimp (Commercial Grade): Canadian and Norwegian products are 40-60% cheaper than Japanese products, suitable for mid-high-end restaurants sensitive to costs, but flavor depth and color typically fall short of Japanese products.

Optimal Raw-Handling Methods
Thawing procedure (key step): Transfer frozen sweet shrimp to 4°C refrigerator, thaw for 4-6 hours (do not thaw at room temperature); optionally soak in 3% saltwater for 5 minutes, gently remove ice crystals; cut along the back of the shrimp, gently peel off the shell, preserving the tail as decoration; the emerald green roe sac on the female's abdomen should be kept intact, as it is the essence of the ingredient.
Plating tips: Sweet shrimp is extremely temperature-sensitive; after shelling, serve immediately to prevent oxidation and discoloration. Plate with shaved ice to maintain low temperature while enhancing visual appeal.
Maximizing Utilization of Shrimp Heads and Roe
Fried shrimp heads (classic preparation): Coat sweet shrimp heads with a thin layer of batter, deep-fry at 180°C until crispy. The tomalley solidifies during frying, creating a crispy texture with rich seafood flavor, making it the most popular side dish at high-end sushi restaurants.
Shrimp head miso soup: Stir-fry shrimp heads in a small amount of oil until golden, add water to make stock, then season with miso. Sweet shrimp heads' rich umami makes for a miso soup beloved by diners.
Shrimp roe (bonus highlight): The orange roe sac on the female's abdomen can be used directly as sashimi garnish, or mixed into sushi vinegar rice for a unique burst of fresh sweetness.
