Upgrade option: Soak 1/2 ounce dried porcini mushrooms in 1/2 cup boiling water for 10 minutes. Reserve the liquid, and add to stock in place of water; cook porcini with button mushrooms.
Serves 4 (serving size: about 1 cup)
1. Bring stock and 1/2 cup water to a simmer in a small saucepan. Reduce heat to low; keep warm.
2. Heat a medium saucepan over medium-high heat. Add oil to pan; swirl to coat. Add onion; sauté 2 minutes or until tender. Add garlic, 2 teaspoons thyme, and mushrooms; cook 4 minutes. Add rice; cook 1 minute, stirring to coat. Add wine; cook 30 seconds, scraping pan to loosen browned bits. Reduce heat to medium-low. Add 1/2 cup stock mixture to pan; cook 4 minutes or until liquid is nearly absorbed, stirring constantly. Add remaining stock mixture, 1/2 cup at a time, stirring almost constantly until each portion is absorbed before adding the next (about 22 minutes). Remove pan from heat. Stir in peas, parsley, mascarpone cheese, vinegar, salt, and pepper. Sprinkle with remaining 1 teaspoon thyme and Parmesan cheese.
