Authentic Thai Red Rubies Recipe – Ingredients and Step-by-Step Preparation

To achieve the most delicious Tub Tim Krob, it is essential to prepare each element with care. The ingredients are simple, but it is the preparation technique that makes all the difference. Below are the core ingredients for a family-sized serving of this dessert, preserving the same traditional taste found in Thai street dessert stalls and royal Thai kitchens:

• 1 cup fresh water chestnuts, diced into small cubes
• 1/2 cup tapioca flour (plus extra for dusting)
• 1/2 cup red food coloring or natural beetroot juice
• 1 cup thick coconut milk
• 1/4 cup sugar (adjust depending on sweetness preference)
• 1/4 teaspoon salt to balance the coconut flavor
• 1–2 cups crushed ice or shaved ice
• Pandan leaves (optional, for enhanced aroma)

Step-by-Step Cooking Process:

1. Soak the diced water chestnuts in red food coloring or beetroot juice for at least 15–20 minutes until they reach a vibrant ruby tone.
2. Drain and coat the colored cubes with tapioca flour until fully covered. Shake off the excess flour before cooking.
3. Boil water in a pot and gently drop the coated cubes into the pot. Stir lightly to prevent sticking. Once the rubies float to the top, continue cooking for another minute before removing.
4. Transfer the cooked rubies to a bowl of ice water to firm up and achieve a chewy-crunchy texture.
5. Prepare the coconut milk by simmering it lightly with sugar, salt, and pandan leaves until aromatic, then let it cool.
6. Assemble by placing the chilled rubies in a bowl, topping with sweetened coconut milk, then finish with crushed ice.

How to Achieve the Perfect Texture and Flavor Balance When Making Tub Tim Krob

The magic of Thai Red Rubies in Coconut Milk comes from its unique texture play—soft, chewy, and crunchy cubes wrapped in tapioca sitting in silky coconut milk. Many people mistakenly use too much flour or overcook the rubies, causing the texture to become gummy instead of pleasantly bouncy. Another common mistake is overly thick coconut milk, which can overpower the dish and make it heavy.

Key tips for getting the texture right:

• Use fresh water chestnuts rather than canned if possible
• Rinse lightly before dusting with flour to help the coating stick
• Keep the ice bath ready before boiling the rubies
• Simmer coconut milk only gently to avoid splitting
• Serve immediately for best mouthfeel

Aside from texture, flavor balance is equally important. The coconut milk should have a mild saltiness that enhances sweetness naturally. This subtle saltiness is a hallmark of many traditional Thai desserts. If pandan leaves are available, they elevate the aroma, giving your dessert an authentic Thai touch.
