Instructions

1. Begin the rice by rinsing it until the water runs clear, then combine it with the coconut milk, water, salt, and pandan leaf in a small saucepan and bring to a simmer before covering and reducing heat to low for 15 minutes.
2. Clean the king oyster mushrooms and slice them lengthwise into thick planks, about a half-inch thick.
3. In a separate small saucepan, combine the rice vinegar, soy sauce, water, brown sugar, sesame oil, thinly sliced ginger, crushed garlic, and star anise for the pickling liquid.
4. Bring the pickling liquid to a boil and immediately pour it over the sliced mushrooms in a heatproof bowl, ensuring they are fully submerged, and set aside to pickle for at least 20 minutes.
5. While the mushrooms pickle, prepare the sambal by roughly chopping the onion, red bell pepper, and garlic.
6. Add the chopped aromatics, rehydrated chilies, tamarind paste, and a splash of oil to a blender and process into a coarse paste.
7. Heat a tablespoon of oil in a small skillet over medium heat, add the sambal paste, and cook, stirring frequently, until it darkens in color and the oil begins to separate, about 8-10 minutes.
8. To assemble, fluff the cooked coconut rice and portion it into bowls.
9. Arrange the pickled mushroom planks over the rice, add a generous spoonful of the bell pepper sambal, and garnish with fresh, thinly sliced cucumber.
10. Finish the dish by coarsely crushing the savory crackers over the top of each bowl and scattering with fresh cilantro or scallions just before serving.

Notes

The hot pickling liquid serves a dual purpose: it gently cooks the mushrooms to a perfect al dente texture while rapidly infusing them with flavor. This technique avoids the sogginess that can come from overcooking mushrooms. If king oyster mushrooms are unavailable, thick-sliced shiitake caps are a suitable alternative, though their texture will be softer.

The final crunch from the crushed crackers is essential for textural contrast against the soft rice and tender mushrooms. A simple, savory cracker like a Hup Seng brand cream cracker adds a familiar, comforting salinity and crispness that is common in Singaporean home cooking. For a more complex, slightly bitter note, use crushed emping (melinjo nut crackers). Serve this bowl immediately for the best contrast between the warm rice and the room-temperature pickled components.
