• Rinse the rice.

In a small sauce pot, combine the rice and 1¼ cups [2¼ cups] water. Bring to a boil, reduce to a simmer, cover, and cook until the rice is tender and the liquid is absorbed, 15 to 20 minutes. Fluff with a fork, cover, and keep warm.
While the rice cooks, prepare the turnips.

• Scrub or peel the turnips; cut the turnips into ¼-inch-thick matchsticks.

In a small sauce pot, bring the rice vinegar and 2 tablespoons [¼ cup] water to a boil. Remove from the heat, add the turnips, and season with salt and pepper. Cover and let stand, stirring occasionally, while you prepare the rest of the meal.

• Cut a small corner from the ground pork packaging and drain off any excess liquid. Transfer to a plate; pat dry with a paper towel.
• Grate or peel and finely chop enough ginger to measure 1 teaspoon [2 tsp].
• Finely chop, press, or grate enough garlic to measure 1 teaspoon [2 tsp].
• Cut the squash in half lengthwise, then crosswise into ½-inch-thick half-moons.
• Trim the root ends from the scallions; thinly slice the scallions on the diagonal for garnish.

In a large frying pan over medium-high heat, warm 1 to 2 tablespoons oil until hot but not smoking. Add the pork, season with salt and pepper, and cook, stirring to break up the meat, until lightly browned but not yet cooked through, 3 to 4 minutes. Stir in the ginger and garlic and cook until fragrant, about 30 seconds.
Add the squash, miso, and 1 cup [2 cups] water and bring to a boil. Reduce to a simmer and cook, stirring occasionally, until the pork is cooked through, the squash is tender, and the sauce is thickened, 3 to 4 minutes. Stir in the “oyster sauce” blend and cook until warmed through, about 1 minute. Remove from the heat and season to taste with salt and pepper.

Transfer the rice to individual bowls and top with the pork and squash. Garnish with the pickled turnips and scallions and serve.
