This sweet-and-sour spinach side dish gets its satisfying flavor from the combination of honey and sherry vinegar that’s drizzled on top. It’s relatively light, which makes it a great addition to a hearty Thanksgiving menu.
Commercial wild mushroom mixes (usually a combination of shiitake, cremini and oyster mushrooms) are a godsend: Some invisible helper has already cleaned, stemmed and sliced the mushrooms for you. In this recipe, they are mixed with spinach and cream, then baked in a luscious gratin under smooth rounds of precooked polenta until bubbling hot.
Curly leaf spinach has great texture and flavor and holds this mustardy dressing well. For additional color, feel free to use a variety of different colored beets. You can also swap blood oranges for the tangerines.
