MACARONI AND CHEESE WITH PROSCIUTTO AND TALEGGIO

Steps:

• Melt butter in heavy large pot over medium heat. Add next 5 ingredients; sauté until tender, about 8 minutes. Add wine and simmer until almost all liquid evaporates, about 10 minutes. Add cream, thyme sprigs, bay leaf and peppercorns; bring to simmer. Reduce heat to low; simmer until slightly reduced, about 15 minutes. Remove from heat. Add Taleggio and Parmesan cheeses. Stir until melted and smooth. Discard bay leaf and thyme sprigs. Cool sauce slightly. Puree sauce in 2 batches in blender until smooth. Strain into same pot. Stir in chopped truffles, if desired. Season with salt and white pepper.
• Preheat broiler. Cook pasta in large pot of boiling salted water until just tender but still firm to bite.
• While pasta cooks, make crumb topping:
• Mix first 3 ingredients in small bowl. Melt butter in heavy medium skillet over medium heat. Add breadcrumb mixture and sauté until golden and coated with butter, about 2 minutes.
• Drain pasta well. Add to sauce along with prosciutto, chives, parsley and 1 teaspoon truffle oil; toss to coat. Mix in additional truffle oil, if desired. Divide macaroni and cheese among 8 individual gratin dishes. Top each with Crumb Topping. Broil until topping is crisp and golden brown, about 2 minutes, and serve.
