Soak the peppers. Soak the peppers in super hot water to rehydrate them. If you want to be extra, you can toast them over a low flame to coax out some extra flavor before soaking.
Season the meat. While the peppers are soaking, season your meat generously with salt and freshly ground pepper.
Make the marinade. Grab your blender and blend together the peppers, garlic, oregano, cumin, beef stock, and vinegar.
Marinate overnight. Marinate as long as you can, or for at least 2 hours so the beef can get super flavorful. Don’t forget to season your beef with salt and pepper first.
Make the stew. Sweat the onions to build up caramelization and sweetness, add the beef (you can sear it if you want, but we’re aiming for soft and tender meat) along with all the marinade, then top it off with extra beef stock, bay leaves, and cloves. Done.
