Meaty shiitakes add a filling note to this fragrant snap-pea accented risotto.
In a saucepan, bring ginger piece, garlic cloves, mushroom and cilantro stems, 1 tablespoon salt, and 8 cups water to a simmer.
In a large straight-sided skillet, heat 2 tablespoons butter over high. Add mushroom caps and a pinch of salt; cook, stirring occasionally, until browned, 5 minutes. Transfer to a bowl; stir in soy sauce. Melt remaining butter in skillet over medium. Add rice and minced ginger and garlic; cook, stirring, until rice is toasted, 3 to 4 minutes. Add wine; cook until evaporated. Add 1/2 cup broth; cook, stirring, until liquid is absorbed. Continue adding broth 1/2 cup at a time, stirring, until rice is al dente, about 25 minutes. Stir in snap peas; cook until tender, about 7 minutes more. Remove from heat and stir in mushroom caps; season with salt and pepper. Serve, with cilantro leaves and a drizzle of soy sauce.
