A reviewed Butter poach / fat poach / low-temp sous vide mapping. Use the method guidance below to choose shrimp, then check the bag’s processing state.
Loses nothing at all - which matters less here than it does for a sweet shrimp.
What to keep in mind
Nothing structural. An assertive sauce is the safest home for a bag that may read iodine-y, and dry heat concentrates rather than dilutes - but whether any method actually masks or exposes bromophenols has never been measured, so this is a hedge and must be labelled as one.
Fat holds no sweetness, so nothing leaves. This is the method the group exists for.
What to keep in mind
Use it cold and dressed. If you want the raw ingredient, buy raw-grade amaebi, which is a different product on the same shelf - that distinction is the single most useful thing the site can tell a reader about this species.

What to keep in mind
Treat it as Group A for every cooked method, and as a raw ingredient only when it arrives alive or air-freighted whole. Its classical cooked preparation, irojime, is worth teaching on its own: live prawns skewered head to tail to stop them curling, dropped into heavily salted water with a splash of vinegar, then shocked in ice.

What to keep in mind
Same as seabob. Note the high surface-to-mass penalty: cook loss runs 28.7% for the smallest grade against 15.8% for the largest, so a gentle medium matters more here than anywhere else in Group A.

What to keep in mind
Rank it first for grill and pan sear. It wins on three measured counts: largest commercial shrimp so the longest browning budget; narrower myofibrillar spacing and lower T2 relaxation so it holds water more tightly and puts less exudate in the way; and higher astaxanthin for a deeper cooked colour.
Fat holds no sweetness, so nothing leaves. This is the method the group exists for.
What to keep in mind
Grill, sear or roast it, one to two minutes a side, pulled early because it carries over. Peel it raw, which is easier than peeling it cooked. Boil-and-drain stays ruled out: a boil flushes the hepatopancreatic fat that California Sea Grant says dry heat exists to keep.
A held temperature cannot overshoot, which is exactly this shrimp's weakness.
What to keep in mind
Treat it as the more fragile member and cook shorter. Two to three minutes in a pan, or simply return the pot to a boil and stop. Do not salt the cooking water - it carries its own salinity from deep water. Note that practitioners report BOTH mushy and rubbery failure modes, not just rubbery.

Processing can change the answer
Precooked (cooked and frozen, or cooked and chilled)
Hardness is an integral of time at temperature, and cook loss, shrinkage and hardness correlate at 97.8, 92.3 and 88.4 percent. Every reheat moves further up the same monotonic curve and nothing re-hydrates.
