Overview
Dried scallops (also known as conpoy, 干贝, or himo-hoshi in various cuisines) are a prized ingredient in Chinese, Japanese, and other East Asian cooking. They are made from the adductor muscle of the scallop — the firm, cylindrical piece of meat that holds the two shells together — which is boiled in salted water and then slowly air-dried over several days to weeks. The result is a concentrated, umami-rich product (roughly 65% protein after drying) used in soups, congee, stir-fries, stocks, and as a garnish. It is prized for its high glutamic acid and nucleotide content, which produces a strong savory flavor.
Source
The core ingredient is the scallop, a bivalve mollusk (shellfish) that lives in the sea. Unlike fish, scallops have no scales or fins; they are enclosed in a shell. Commercial dried scallop products are typically just the adductor muscle plus salt from the boiling/curing process. Some commercial dried or "wet" fresh scallops may also be treated with sodium tripolyphosphate (STPP) as a preservative/water-retention agent, though genuine dry-processed scallops used for conpoy are usually chemical-free. Some packaged or seasoned dried-scallop products may include added MSG or flavoring agents, whose own source (plant, synthetic, or animal-derived) would need separate verification.
Islamic Ruling — Scholarly Differences Exist
This ingredient has differing scholarly opinions rooted in a long-standing fiqh debate over shellfish (non-fish sea creatures) rather than in any impurity of the scallop itself. Muslims should be aware of these differences and follow their preferred madhab or a trusted local scholar.
Madhahib Perspectives
Hanafi School: The dominant Hanafi position treats scallops as not permissible (haram or at least strongly makrooh). Hanafi jurists generally restrict halal sea creatures to "fish" (samak) only; because scallops are a shelled mollusk without scales or fins, they are classified with oysters, mussels, and other non-fish shellfish, which most Hanafi scholars exclude from what is lawful to eat from the sea.
Maliki School: Maliki scholars are generally permissive toward sea creatures. The mainstream Maliki view holds that all creatures of the sea are lawful, which would include scallops, though some individual Maliki opinions have historically carried reservations about certain non-fish sea life.
Shafi'i School: The Shafi'i school is explicitly permissive here. Imam al-Shafi'i's position is that all sea creatures are halal except those specifically excluded (frogs, and creatures considered inherently harmful or repugnant, such as some accounts add crocodiles/turtles in certain formulations). Scallops fall under the general permission, so most Shafi'i-following communities regard them as halal.
Hanbali School: The Hanbali school likewise takes the broadly permissive view that anything living in the sea is lawful to eat, again barring specific exclusions. Scallops are therefore generally halal under mainstream Hanbali fiqh.
Important Considerations
- The disagreement is genuine and long-standing — this is not a fringe or resolved debate. Since a large share of the global Muslim population follows Shafi'i, Maliki, or Hanbali fiqh, dried scallops are widely treated as halal in many Muslim communities; Hanafi-following Muslims, however, are commonly told to avoid them.
- Drying and processing do not change the underlying shellfish classification — boiling and salt-curing the adductor muscle does not transform scallops into "fish" for Hanafi purposes, so the same school-based disagreement applies to the dried/conpoy form as to fresh scallops.
- Added ingredients matter — some dried scallop products may include MSG, flavor enhancers, or preservatives (e.g., STPP in some scallop processing) whose halal status depends on their own source; check labels and prefer certified products when available.
- When in doubt, follow your madhab or a local scholar — because this hinges on a genuine classical fiqh dispute rather than an impurity issue, the safest approach for someone unsure of their school's ruling, or seeking the more cautious position, is to avoid non-fish shellfish like scallops or to seek specific local guidance.
