MAKE-AHEAD MARSALA TURKEY GRAVY

Steps:

• Heat oil in a Dutch oven over medium-high heat. Place turkey necks in the Dutch oven and cook until golden brown, 5 to 7 minutes. Stir in onion, celery, and carrot; cook and stir until onion is soft and slightly brown, about 5 minutes.
• Pour Marsala wine over turkey necks; increase heat to high and bring to a boil while scraping the browned bits off of the bottom of the pan. Simmer until wine is reduced by half, 3 to 4 minutes.
• Stir in water, 1/4 ounce dried porcini mushrooms, garlic, and bay leaf. Bring to a boil then decrease heat to low; simmer, skimming any foam or fat that rises to the top. Cover the Dutch oven almost completely; simmer until meat is falling off the bones, 4 to 5 hours. Strain turkey stock carefully into a clean container and cool completely, about 2 hours.
• Place 1/4 ounce dry porcini mushrooms in a bowl and cover with warm water; soak until mushrooms are soft enough to dice, about 15 minutes. Drain, squeezing out excess water, and dice. Set aside.
• Melt butter in saucepan over medium heat. Add diced porcini mushrooms; cook and stir until browned, about 5 minutes.
• Stir flour into mushrooms and butter; cook and stir until flour is no longer gritty, about 3 minutes.
• Whisk in turkey stock, increase heat to medium-high and bring to a simmer. Simmer, stirring occasionally, until sauce is 1/3 reduced and thick, 15 to 20 minutes. Stir in cream, season with salt and pepper to taste.
