Toast and grind the rice: Heat a small dry skillet over medium heat. Add the 1/4 cup uncooked rice and toast, stirring or shaking the pan constantly, until the grains are evenly golden-brown and smell nutty — about 3–5 minutes. Toasting concentrates flavor and removes rawness; it also makes the ground rice slightly porous so it will thicken the dressing and add mouthfeel. Remove to a plate to cool completely.

Grind the toasted rice to a coarse powder: Once cooled, transfer the toasted rice to a spice grinder or mortar and pestle and grind to a coarse powder (some tiny granules are good — you want texture). If you grind it superfine it will act more like a starch thickener; leaving some texture gives a pleasant nutty grit that clings to greens and noodles.

Prep aromatics: Mince the garlic and finely mince the red onion. Mincing releases juices and surface area so the aromatics will perfume and flavor the dressing evenly; do this first so the flavors can briefly macerate while you finish other steps.

Bloom the aromatics with the vinegar and soy: In a medium bowl, whisk together rice vinegar (3 tbsp), low-sodium soy sauce (2 tbsp) and honey (1 tbsp) until the honey dissolves. Add the minced garlic and red onion and let sit 2–3 minutes. Acidic liquids (vinegar) macerate onion and garlic slightly, mellowing sharp raw edges and marrying flavors.

Emulsify the oils: Slowly whisk in the neutral oil (3 tbsp) a little at a time, then whisk in the toasted sesame oil (1 tbsp). Whisking the oil into the acid base slowly creates a stable emulsion so the dressing is smooth and glossy rather than split. If you prefer, you can add the oils to a jar, pour in the vinegar mixture, and shake vigorously for 30–45 seconds.

Add toasted rice powder and sesame seeds: Fold in the ground toasted rice and the 1 tbsp toasted sesame seeds, then season with 1/2 tsp freshly ground black pepper and 1/4 tsp salt (or to taste). The toasted rice acts as a natural thickener and adds a toasted, slightly crunchy element; sesame seeds add nuttiness and visual interest.

Adjust consistency and balance: If the dressing is too thick, whisk in 1–2 tbsp warm water at a time until you reach desired pourable consistency. Taste and adjust — add a splash more vinegar for brightness, a pinch more salt or a drizzle more honey if too tart. Warm water helps the honey and oils blend smoothly and loosens the toasted rice without diluting flavor.

Rest and serve: Let the dressing rest 10–15 minutes at room temperature so flavors meld and the toasted rice slightly softens. Re-whisk or shake just before serving. Store in a sealed jar in the fridge up to 5 days; bring to room temperature and re-whisk before using.

Serving suggestions: Drizzle over mixed greens, cold sesame noodles, steamed broccoli, or use as a finishing sauce for grilled salmon or tofu. The crunchy bits of toasted rice are a signature textural element — spoon any settled solids from the jar back into the mix before serving.
