Potato Moussaka With Bolognese Sauce

• Bolognese Sauce (double batch)
• 1 large onion
• 2 large carrots
• 3 stalks celery
• 3-4 cloves garlic
• 2-3 tablespoons cooking fat (I used tallow)
• 2 pounds ground lamb or beef
• 1 cup tomato paste (8 oz)
• 2 cups full-bodied red wine
• few sprigs of fresh thyme
• salt, fresh ground black pepper to taste
• 1/2 teaspoon ground cumin (optional)
• 1/4 teaspoon ground cloves (optional)
• 1-2 bay leaves
• Custard, Layering and Topping (for one pie)
• 3 large eggs
• 1 cup half-and-half, or a 50/50 mix of cream and milk
• 1/4 cup grated cheese, such as Pecorino, Romano, Parmesan, or crumbled Feta
• 1/4 cup bread crumbs
• 2 pounds potatoes, peeled and sliced 1/8" thick

1. Make mirepoix (flavor base). Chop carrots, onions, celery and garlic finely. Heat the cooking fat in a Dutch oven over medium-low. Add vegetables, sprinkle a bit of salt and pepper over and saute for full 15 minutes, stirring frequently, until vegetables lose their color and brown nicely. Flavors will be very prominent and rich. It pays off to take care and time at this phase as vegetables will lend their aroma and flavor to everything else.
2. Add ground meat at this point, breaking it down with a spatula and combining with the mirepoix. Sprinkle a bit more salt and pepper over, and cook slowly, until most of the juices evaporate and meat is nicely browned. 10-12 minutes is a must.
3. Add tomato paste and stir it in thoroughly. Cook for another 4-5 minutes or so.
4. Add red wine. Scrape the bottom of the pot with a spatula to deglaze. Stir well, and cook for another 5 minutes.
5. Add just enough water to cover the meat, toss in thyme sprigs and bay leaves. Add cumin and cloves if desire.
6. Bring the sauce to a boil, reduce heat to very low, check for seasoning and correct if needed.
7. Simmer, uncovered, for at least 1-1/2 to 2 hrs, stirring occasionally, until sauce becomes thick, rich, and turns burgundy-brown in color. The final sauce should be about the thickness of pancake batter, rich but not greasy, all flavors well developed and blended. This is the state that only can be described as "you'll know when it's done, because you won't be able to put the spoon down tasting it".Just a little reminder, this batch of sauce is double size, so if you are not planning on using the entire batch, divide it in half and reserve one half for other time.
8. Cover peeled and sliced potatoes with cold water in a pan, bring to a boil and boil for 5 minutes.
9. Drain potatoes immediately and rinse in cold running water to prevent further cooking.
10. Grease a lasagna pan or a 9x13? casserole dish with cooking fat on the bottom and sides.
11. Put down the a layer of potatoes, overlapping if needed to cover the bottom completely.
12. Sprinkle salt and fresh ground pepper over the potatoes.
13. Pour down half of the Bolognese over the potatoes and spread evenly with the back of the ladle.
14. Repeat steps 11-12-13, then 11-12 again.
15. Prepare the custard mix by whisking the eggs and half-and-half in a bowl.
16. Pour the custard mix over the pie evenly distributing it all over.
17. Spread the bread crumbs and the cheese over the top.
18. Bake Moussaka at 375F for about 50 minutes, or until the potatoes are cooked through (fork tender) and top is nicely browned. Let stand for 10 minutes out of the oven before serving.
