01 - Combine ground beef and water in a large stockpot. Break up meat thoroughly with a wooden spoon—do not brown the beef. The unique texture comes from simmering raw meat.
02 - Stir in chopped onion, garlic, tomato sauce, tomato paste, Worcestershire sauce, vinegar, brown sugar, and all spices including cinnamon, cocoa powder, allspice, cumin, cloves, and cayenne. Mix until well combined.
03 - Bring mixture to a gentle boil over medium-high heat, then reduce to low. Simmer uncovered for 1 hour 30 minutes, stirring occasionally. Skim any fat that rises to the surface during cooking.
04 - Remove bay leaf and taste the chili. Adjust salt or spice levels as needed. The flavors should be rich and deeply spiced with Mediterranean undertones.
05 - While chili simmers, cook spaghetti in salted boiling water according to package directions until al dente. Drain well in a colander and set aside.
06 - Layer cooked spaghetti in bowls and ladle hot chili sauce over pasta. Top with cheddar cheese, diced onions, and kidney beans as desired. Two-way: spaghetti and chili; Three-way: add cheese; Four-way: add onions or beans; Five-way: add both onions and beans.
