Ingredients

• 1 (13.5 oz / 400ml) can full-fat coconut milk (or `best coconut milk` you can find)
• 1/4 cup (50g) granulated sugar (adjust to taste)
• Pinch of salt (about 1/8 teaspoon)
• 1 tablespoon (8g) cornstarch (or tapioca starch for a glossier finish)
• 2 tablespoons (30ml) cold water
• 1/2 teaspoon vanilla extract (optional, or pandan extract for a different flavor)

Directions

1. Combine & Heat: Pour the full-fat coconut milk into your saucepan. Add the granulated sugar and salt. Place the saucepan over medium heat, whisking gently until the sugar and salt are fully dissolved. You’ll notice the mixture becoming fragrant and steaming lightly, but avoid bringing it to a rolling boil just yet. (Imagine a visual aid here: coconut milk, sugar, and salt in a saucepan on a stove.)
2. Prepare Slurry: In a small separate bowl, whisk together the cornstarch (or tapioca starch) and cold water until you have a smooth, lump-free slurry. This is your thickening agent!
3. Whisk & Simmer: Once the sugar is dissolved in the coconut milk, slowly pour the cornstarch slurry into the saucepan while continuously whisking the coconut milk mixture. Continue to whisk over medium heat. The sauce will begin to thicken quite quickly, usually within 1-2 minutes. Look for it to coat the back of a spoon, or for it to gently bubble and thicken to your desired consistency. It should be noticeably thicker than plain milk. (Imagine a visual aid here: pouring slurry into simmering coconut milk while whisking.)
4. Cool & Flavor: Remove the sauce from the heat. Stir in the vanilla extract (if using). For serving with `hawaiian sweet buns`, you'll want the sauce to be warm, not piping hot. Let it cool for 5-10 minutes, stirring occasionally, until it reaches a comfortable temperature for drizzling or soaking. If you're making it ahead, transfer it to a thermal bowl or a clean container to cool further before chilling. (Imagine a visual aid here: warm sauce being poured over buns or into a serving dish.)
