Thai Boy Red Lime Stone (Calcium Hydroxide) 100g

Thai Boy Red Lime Stone (Calcium Hydroxide) 100g

Thai Boy Red Lime Stone (ปูนแดงตราไทยบอย, pun daeng tra Thai Boy) is a traditional Thai culinary ingredient produced under the Thai Boy brand. Red lime stone (pun daeng / ปูนแดง) is food-grade calcium hydroxide (Ca(OH)₂) in a red-coloured form — the red colour is derived from the addition of 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 daeng / น้ำปูนแดง), 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. Red lime stone is also used in traditional Thai betel nut (mak / หมาก) preparations, where it is applied to betel leaves as part of the traditional chewing preparation. 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.
