How to Make It
Combine flour, salt, cumin, coriander, cinnamon, and turmeric in a small bowl. Rub spice mixture on all sides of stew meat.
Heat 2 tablespoons of the oil in a Dutch oven over medium-high. Cook half of the meat, stirring occasionally, until browned, about 5 minutes. Transfer to a plate. Repeat with remaining oil and meat.
Add squash, onion, and garlic to Dutch oven over medium, and cook, stirring occasionally, until fragrant, about 3 minutes. Stir in stock, tomatoes, vinegar, and bay leaf; bring to a simmer, scraping up any browned bits from bottom of Dutch oven. Add stew meat; cover and cook, stirring occasionally until tender, about 1 hour and 20 minutes.
