Khao Kriab Gung (ข้าวเกรียบกุ้ง)

ข้าวเกรียบกุ้ง

Light, airy prawn crackers made the traditional way — from a spiced shrimp paste and tapioca dough that's steamed, sun-dried, then deep-fried into crispy, puffed crisps with intense prawn flavour.

Making prawn crackers from scratch is a time-honoured process across Southeast Asia. The Thai approach typically uses pure tapioca starch combined with fresh prawns pounded to a paste, creating crackers with clean shrimp flavour and the characteristic light, airy texture that makes them so addictive.

The process spans several days: first making and steaming the prawn dough, then slicing and drying the cooked logs until completely dehydrated, and finally the quick frying that transforms hard discs into puffed, golden crackers in seconds.

Base

Frying

The Method

1. Make prawn paste. Peel prawns completely, devein, wash thoroughly. Pat dry and blend to a smooth, fine paste in food processor. Pound garlic to a paste; combine with prawn paste.
2. Make the dough. Mix tapioca flour, salt and white pepper in large bowl. Add prawn-garlic paste and work into flour mixture. Gradually add hot water while kneading until smooth, elastic dough forms (10-15 minutes kneading). Dough should be stiff but not crumbly — add more water if needed.
3. Steam and chill. Roll dough into fat logs about 4-5cm diameter. Wrap tightly in aluminium foil or cling film. Steam over boiling water for 1 hour until cooked through. Cool completely, then chill overnight in fridge until firm.
4. Dry the crackers. Slice chilled logs into very thin discs (1-2mm thick). Arrange on drying racks in single layer. Sun-dry 2-3 days until completely brittle and dry. Alternatively: dehydrator at 60°C for 4-5 hours, or oven at 50°C until dry.
5. Fry and serve. Heat oil to 180°C for deep frying. Fry dried crackers in small batches — they puff immediately. Remove as soon as puffed and golden (seconds only). Drain on paper towels; serve immediately while crispy.

The technique

Prawn preparation matters. Use the freshest prawns available — white prawns (กุ้งขาว) are preferred for their sweet, clean flavour. Some traditional recipes keep the head fat for extra aroma. Pound or blend to a smooth paste; any chunks will create weak spots in the crackers.

Dough development is key. Thorough kneading develops the protein structure that allows crackers to puff properly. The dough should be stiff but smooth and elastic after 10-15 minutes of work. Too wet and the crackers won't hold their shape; too dry and they won't puff.

Steaming sets the structure. The hour-long steam cooks the starch and sets the prawn proteins, creating the firm texture needed for clean slicing. Cool completely before cutting — warm dough will tear.

Drying is essential. Crackers must be bone-dry before frying or they'll turn chewy instead of crispy. In Thailand's sun, this takes 2-3 days. Modern alternatives include dehydrators or low ovens, though sun-drying gives the best texture.

Frying happens fast. At the right temperature (180°C), crackers puff within seconds. Watch closely — over-fried crackers turn dark and bitter.

Variations across sources

Traditional recipes show interesting regional differences. Northern approaches often include rice flour alongside tapioca for a slightly different texture. Southern variants may add curry powder or dried chilli for heat. Modern versions sometimes include baking powder for extra puff, though purists argue this changes the authentic texture.

The prawn-to-flour ratio varies significantly between sources — from economical versions using 300g prawns to 450g flour, to luxury versions with equal weights for maximum seafood flavour.

Flavouring additions range from simple garlic and white pepper to more complex combinations including oyster sauce (for umami depth) or shrimp paste (for extra marine intensity).

Storage and serving

Dried, unfried crackers keep for months in airtight containers — perfect for making large batches when prawns are abundant and cheap. Fry only what you'll eat immediately; once fried, crackers go stale within hours.

Serve alongside som tam, larb, or any Thai meal as a crunchy counterpoint to fresh flavours. They're also excellent as a snack with sweet chilli sauce or simply enjoyed plain to appreciate the concentrated prawn taste.

Cook's notes

• Equipment needed: Food processor or large mortar, steamer, sharp knife, dehydrator or drying racks, deep-frying setup
• Timing: Plan 3-4 days ahead for traditional sun-drying
• Economics: Expensive to make but premium quality compared to commercial versions
• Success markers: Crackers should puff dramatically when dropped in hot oil, becoming light and airy with no dense spots

The satisfaction of homemade prawn crackers — from the aromatic prawn paste through the patient drying process to that magical moment when hard discs transform into gossamer crisps — makes this one of Thai cuisine's most rewarding traditional preparations.

Cook's Tips

• White prawns (กุ้งขาว) give the best aroma
• Knead dough thoroughly — well-developed gluten makes crackers puff better
• Slice evenly for uniform cooking
• Store dried crackers airtight for months before frying
• For extra crispness: first fry on medium heat, rest 5 minutes, quick second fry
• Watch carefully when frying — they puff within seconds
