For 13.5 fl oz coconut milk
Ingredients
13.5 fl oz full-fat unsweetened Thai coconut milk (Aroy-D 100% or Chaokoh), well stirred
4 to 5 tbsp cold water
5 1/2 to 6 tbsp chia seeds (5 1/2 for looser, 6 for firmer)
3 tbsp palm sugar syrup
1/4 tsp fine sea salt
2 fresh pandan leaves, knotted, or 1/4 tsp pandan extract as fallback
1/4 tsp finely grated lime zest, optional
Palm sugar syrup
2 oz palm sugar by weight, chopped if disc form
2 oz water
Coconut sauce
1/3 cup coconut cream (the thick top from a separated can, or a small can of dedicated coconut cream)
Pinch of fine sea salt
1 tsp palm sugar syrup, optional
Toppings, per serving
1/4 to 1/3 ripe Ataulfo or Champagne mango, diced
1 to 2 tbsp coconut sauce
1 tsp toasted unsweetened coconut flakes or 1 tsp toasted black sesame seeds
Tiny pinch of flaky salt
Small squeeze of lime, optional
Make the palm sugar syrup
Combine the palm sugar and water in a small saucepan over low heat. Stir until the sugar fully dissolves. Do not boil. Cool to room temperature. The syrup keeps 2 weeks refrigerated and is the workhorse of every Thai dessert you make.
Infuse the coconut milk
This is the move that turns a flavored chia pudding into something Thai.
If using fresh pandan, warm the coconut milk in a small saucepan with the knotted leaves over the lowest heat for 5 to 7 minutes. The milk should feel hot to the touch but never simmer. Pull the leaves out and let the milk cool to room temperature.
If using pandan extract, skip the warming and stir the extract in at the next step.
Build the pudding base
In a wide bowl or large jar, whisk together the infused coconut milk, water, palm sugar syrup, salt, optional lime zest, and pandan extract if you went that route. Whisk until you cannot see streaks of cream or syrup.
Add the chia seeds. Whisk hard for 30 seconds.
Whisk and rest, three passes
Rest the bowl uncovered for 5 minutes. Whisk hard again for 30 seconds, scraping the seeds clinging to the sides.
Rest 15 minutes. Whisk a final time.
This three-pass routine is non-negotiable. Skip it and the chia clumps at the bottom while the liquid sits clear on top.
Chill
Cover and refrigerate for at least 4 hours, ideally overnight. The pudding holds 3 to 4 days refrigerated.
Make the coconut sauce
Whisk the coconut cream with a pinch of salt and the optional 1 tsp palm sugar syrup until smooth and lightly glossy. Do not heat. Refrigerate until service.
Serve
Stir the pudding once before plating. It should look like loose porridge with the chia fully bloomed — not gel cubes, not soup. If it set too firm, slacken with a tablespoon of cold coconut milk and stir.
Spoon into bowls or glasses. Top with diced mango, a drizzle of coconut sauce, and a small mound of toasted coconut flakes or black sesame seeds. Finish with a tiny pinch of flaky salt and a squeeze of lime if using.
Eat cold.
Notes
Aroy-D 100% (no stabilizers) is the gold standard. Chaokoh full-fat is the fallback. Reduced-fat coconut milk reads thin and the dessert loses its body. Avoid anything labeled "lite."
Fresh pandan steeped warm is the move. Extract is a usable fallback. The two are not the same — fresh pandan carries a layered floral aroma that extract approximates and does not replicate.
Palm sugar at 1:1 by weight gives a syrup that is sweet but not aggressive. White sugar reads flat here. Brown sugar is acceptable but loses the molasses-floral note that palm sugar carries.
Salt at 1/4 tsp in the base, plus a finishing pinch at service, is the salt-sweet axis Thai desserts run on. Skip either and the pudding reads flat.
Ataulfo or Champagne mango approximates Thai nam dok mai better than Tommy Atkins or Kent. Indian Alphonso, if the season is right, is closer still. Avoid stringy varieties.
Pandan extract varies wildly between brands. Koepoe Koepoe is aggressive at 1/4 tsp. Some Vietnamese brands are mild. Start at 1/8 tsp and add to taste.
Top at service, not before. Mango sitting in chia pudding goes mushy and the textures collapse into one note. The contrast between cool firm pudding, juicy fruit, and crisp seed is the whole point.
Pour the coconut sauce in a deliberate spiral, not a dollop. The visual draws from the way coconut sauce pools around mango sticky rice. Shape matters.
