1 ½cups long-grain white rice, such as Carolina or jasmine
Salt and pepper
2tablespoons butter, plus more to butter the baking dish
1cup grated Parmesan
½cup slivered almonds
1cup ricotta
1cup grated Gruyère or other Swiss cheese
¼cup currants
Pinch of grated nutmeg
1teaspoon grated lemon zest
1teaspoon chopped thyme
1teaspoon chopped sage
Bring a large pot of well-salted water to a boil. Add spinach and wilt for 30 seconds. Remove with a wire mesh spider or tongs and rinse in a colander with cold water. Squeeze dry and chop roughly.
In the same pot, boil the rice for 10 minutes, keeping it slightly underdone. Drain and spread on a baking sheet to cool, then transfer to a large bowl.
Heat oven to 375 degrees. Butter a 2-quart soufflé dish (or other baking dish) and dust with about 2 tablespoons grated Parmesan.
Melt 2 tablespoons butter in a small skillet over medium heat. Add almonds and cook, stirring, until golden, about 2 minutes. Season lightly with salt and add contents of skillet to rice.
Add remaining Parmesan to rice, along with the ricotta, Gruyère, currants, nutmeg, lemon zest, thyme and sage. Season lightly with salt and add pepper to taste. Add chopped spinach and gently toss rice with hands or wooden spoons to distribute ingredients evenly. Transfer mixture to prepared baking dish. (May be prepared up to this point several hours in advance of baking.)
Cover and bake for 30 minutes, then uncover and bake 10 minutes more, until top is browned.
