ทับทิมกรอบ: Easy Thai Ruby Dessert Recipe for Beginners

Introduction

ทับทิมกรอบ (Tub Tim Grob) is a beloved Thai dessert known as “crispy rubies” — sweet, colorful water chestnut bites coated in translucent tapioca and served in creamy coconut milk with ice. This beginner-friendly recipe walks you through each step clearly so home cooks can recreate authentic ทับทิมกรอบ at home. It’s refreshing, visually beautiful, and perfect for warm days or as a light finish to a Thai meal.

Ingredients for ทับทิมกรอบ

• 250 g water chestnuts (fresh, canned, or pre-cooked), diced into small cubes (about 0.5 cm)
• 1 cup (120 g) tapioca flour/starch + extra 2–4 tbsp for dusting
• 1 cup (240 ml) water
• 1/2 cup (100 g) granulated sugar (for poaching)
• 2–3 drops red food coloring (or natural beet juice) — adjust for desired color
• 400 ml canned coconut milk (full-fat for creamier texture)
• 2–3 tbsp palm sugar or granulated sugar (to sweeten coconut milk)
• Pinch of salt
• Ice or crushed ice, for serving
• Pandan leaves (optional) for aroma while warming coconut milk
• Optional garnish: roasted sesame seeds or shredded coconut

Instructions to make ทับทิมกรอบ

1. Prepare the water chestnuts: If using fresh, peel and dice into small even cubes. If canned, drain and rinse, then dice if needed.
2. Make the poaching syrup: In a saucepan, combine 1 cup water and 1/2 cup sugar. Bring to a gentle boil, stirring until the sugar dissolves.
3. Poach the chestnuts: Add the diced water chestnuts to the syrup, simmer for 2–3 minutes to let them absorb a little sweetness. Add red food coloring and stir gently until evenly colored. Remove from heat and drain the chestnuts into a colander, reserving a little syrup if you’d like to sweeten the final dish.
4. Coat with tapioca: Place 1 cup tapioca flour in a shallow bowl. While the poached chestnuts are still slightly wet, toss small batches in the tapioca flour to coat each cube thoroughly. Shake off excess flour. Use extra tablespoon(s) of tapioca flour if pieces stick; you want each piece evenly dusted but not caked.
5. Boil to set the coating: Bring a pot of water to a rolling boil. Carefully drop coated chestnuts into the boiling water in small batches. Stir gently so they don’t stick. Cook until the tapioca coating turns translucent and the pieces float (about 30–60 seconds).
6. Shock in ice water: Using a slotted spoon, transfer the cooked pieces immediately into a bowl of ice water to stop cooking and set the chewy, translucent outer layer. Let them cool for 1–2 minutes, then drain and set aside.
7. Prepare the coconut milk sauce: In a small saucepan, warm the coconut milk gently with 2–3 tbsp palm sugar (or granulated sugar) and a pinch of salt. Add a pandan leaf for fragrance if using. Do not boil — just warm until sugar dissolves. Remove pandan and cool to room temperature or chill.
8. Assemble and serve: In serving bowls, place a generous spoonful of ทับทิมกรอบ, add crushed ice, pour chilled or room-temperature sweetened coconut milk over, and drizzle a little reserved syrup if you kept some. Serve immediately.

Cooking Tips for Perfect ทับทิมกรอบ

– Work in small batches when coating and boiling so pieces cook evenly and don’t clump together.
– Use freshly sifted tapioca flour to avoid lumps; a light dusting is better than a heavy clump.
– If the outer layer breaks during boiling, it usually means pieces were over-coated or boiled too long — reduce coating next time and watch the water closely.
– For natural red color, use a small amount of beet juice diluted with a little water; a few drops go a long way.
– Chill the coconut milk before serving for an extra-refreshing dessert, or serve room temperature with crushed ice for contrast.
– Leftovers: Keep tubtim krob and coconut milk separately in airtight containers in the fridge for up to 2 days; textures are best fresh.
