Start the rice: Rinse the 150 g short-grain brown rice under cold water until the runoff runs near clear to remove surface starch — this prevents gummy rice. Combine the rinsed rice with 375 ml water in a medium saucepan, bring to a gentle boil, then reduce to the lowest simmer, cover and cook for 30–35 minutes until tender. Rest, covered, 10 minutes off heat to let steam finish the grain (this step lets the starches settle so the rice is separate and chewy).

Make the scallion oil: While the rice starts, thinly slice 2 medium scallions. Heat 2 tsp (≈10 ml) neutral oil in a small saucepan until shimmering but not smoking (about 160–170°C / 325–340°F). Put the scallions in a heatproof bowl and carefully pour the hot oil over them — it will sizzle and soften the scallions and release an oniony aroma. The quick-bloomed scallion oil gives bright aromatics to finish the bowl. Reserve both oil and softened scallions.

Prep tofu and aromatics gently: Drain the 300 g silken tofu in a colander placed over a bowl for a few minutes, then transfer to a plate and cut into 2-cm cubes using a thin knife. Silken tofu is fragile — minimal handling prevents it from falling apart. Mince 1 clove garlic and 1/2-inch ginger and measure the 1 tsp ground Sichuan pepper & chili-bean blend.

Sauté the spinach: Heat 1 tsp of the reserved neutral oil or a quick spray in a wide skillet over medium-high. Add the 120 g baby spinach in batches, tossing just until wilted (about 1–2 minutes total). Season lightly with a pinch of salt to draw moisture and enhance flavor. Quick sauté preserves the green color and tender texture — overcooking makes it soggy. Transfer to a bowl and keep warm.

Build the mapo-style sauce: In the same skillet, add the remaining 1 tbsp neutral oil and warm over medium heat. Add the minced garlic and ginger; cook 20–30 seconds until fragrant — this blooms their aromatics. Add the 1 tsp ground Sichuan pepper & chili-bean blend and stir for 20–30 seconds to release its oils and deepen the flavor (blooming spices in oil is essential for aromatic intensity).

Deglaze and season: Pour in 60 ml vegetable stock (or water) and the 2 tsp soy sauce, plus 1/4 tsp sugar (if using) to balance heat and salt. Bring to a gentle simmer. Taste and adjust: you want a savory, slightly spicy umami base that will carry the tofu — not overpower it.

Gently warm the tofu in the sauce: Carefully slide the silken tofu cubes into the simmering sauce. Warm them for 2–3 minutes without boiling — vigorous boiling will break silken tofu into mush. Warmth allows the tofu to absorb flavors while keeping its silk-smooth texture.

Optional thickening (delicate): If you prefer a slightly glossy sauce to cling to the tofu, make a cornstarch slurry by mixing 1/2 tsp cornstarch with 1 tbsp cold water. Stir the slurry again and drizzle 1 tsp at a time into the pan, stirring gently, until the sauce lightly thickens. Use minimal slurry to avoid overpowering the tofu with starch; the goal is a silky, not gloopy, coating.

Finish with oils for fragrance: Turn off the heat and stir in 1 tsp sesame oil and the reserved scallion oil (pour in the hot oil and the softened scallions). The toasted sesame oil adds nuttiness; the scallion oil returns a lively, fresh top note. Adjust seasoning with a small pinch of salt only if needed — soy already contributes saltiness.

Assemble the bowls: Spoon half the cooked brown rice into two bowls, top each with half the sautéed spinach, then carefully arrange half the warmed silken tofu cubes and ladle some of the mapo-style sauce over each. Scatter softened scallions from the scallion oil and an extra pinch of ground Sichuan pepper or chili-bean blend if you want more heat. Finish with a small drizzle of scallion oil and a few drops of sesame oil for sheen.

Serve and eat: Serve immediately while warm. Encourage diners to break a tofu cube with their spoon so the silky center mingles with rice and spinach — that texture contrast is the heart of this bowl.
