Thai Boy White Lime Stone (Calcium Hydroxide) 100g

Thai Boy White Lime Stone (Calcium Hydroxide) 100g

Thai Boy White Lime Stone (ปูนขาวตราไทยบอย, pun khao tra Thai Boy) is a traditional Thai culinary ingredient produced under the Thai Boy brand. White lime stone (pun khao / ปูนขาว) is food-grade calcium hydroxide (Ca(OH)₂) in its natural white, uncoloured form — the white variant contains no added plant extracts, distinguishing it from the red lime stone (pun daeng) variant which is coloured with natural plant extracts. Calcium hydroxide has been used in Thai cooking and traditional practices for centuries. In culinary applications, it is used by dissolving a small amount in water to produce lime water (nam pun khao / น้ำปูนขาว), using only the clear settled liquid above the sediment. Lime water is used in Thai dessert making to firm textures and maintain crispness in batters and vegetables, and to produce the characteristic light, airy crunch in Thai fried snacks and fritters. The white variant is suited to applications where no additional colour is desired in the final dish, making it more versatile for light-coloured batters and desserts where the red variant’s colour would be visible. The 100g pack is a standard household format — a small quantity is sufficient for many uses as only a small amount is dissolved per preparation.

• Product type: Food-grade calcium hydroxide (white lime stone / pun khao) — Thai Boy brand, traditional Thai culinary ingredient, 100g
• Key culinary use: Thai dessert and sweet making — lime water from white lime stone firms textures, maintains crispness, and adds a light, airy quality to batters and fried snacks without adding colour
• Primary use case: Thai khanom (sweets and desserts) and crispy batter preparation — dissolve in water, allow to settle, and use only the clear liquid for soaking or batter applications
• Secondary use case: Vegetable preparation — soaking vegetables in lime water helps maintain crispness and colour during cooking
• Pack size: 100g — standard household format; use sparingly as a small amount is sufficient per preparation

Usage note: Dissolve a small amount in water to create lime water (nam pun khao). Allow to settle fully and use only the clear liquid above the sediment — do not use the sediment directly. Use only as directed in recipes. Store in a cool, dry place away from moisture. Keep out of reach of children.
