Golda Prawn (scientific name: Macrobrachium rosenbergii) is most commonly called a Giant Freshwater Prawn. When you have a size of 5 pieces per kilogram, these are considered Jumbo or Colossal grade. In the seafood industry, this specific grading is often labeled as U/6 (meaning "under 6 per kilo").1. Description
Size: These are massive prawns, often reaching the size of a small lobster tail. Each individual prawn weighs approximately 170-220 grams.
- Physical Features: They are easily identified by their very long, blue-tinted claws and a large head.
- Texture: The meat is firm, white, and meaty—very similar to lobster.
-
Flavor: It has a sweet, delicate taste. The head contains a rich, orange "creamy" substance (often called prawn butter), which is highly prized for making sauces.
2. Why are they called "Lobster"
In many Asian markets, you will see them labeled as "Freshwater Lobster" or "Scampi". While they look like lobsters because of their size and claws, they are technically prawns that live in rivers and lakes.
Best Ways to Cook (U/6 Size)
Because they are so large, they are best prepared in ways that showcase their size:
Golda Chingri Malaikari: The classic Bengali dish using coconut milk and spices.
- Grilled/Barbecued: Split them down the middle (Butterfly style) and grill them with garlic butter and lemon.
-
Tandoori Prawns: Marinated in yogurt and spices and roasted in an oven.
4. Buying Tips
Head-On vs. Headless: These are almost always sold "Head-On" because the head's flavor is essential for traditional curries.
- Frozen Blocks: In the UK or USA, you will find these in the frozen section of Bangladeshi or Indian stores, usually packed in 1kg or 2kg boxes.
