Cooking German Chili Con Carne in Mike's Expat Kitchen

Of course chili con carne isn't German, but I have a good story to explain why I'm cooking it! Here's the recipe:
1 lb ground beef
4 dried chili peppers
1 cup chicken broth
1 onion2 cloves of garlic, chopped
1 strip lemon peel
2 tablespoons tomato paste
2 tablespoons ketchup
12 oz diced tomatoes (canned)
12 oz pinto beans (canned)
1/2 teaspoon coriander
1-2 teaspoons cayenne pepper
1/2 teaspoon cumin
1/2 teaspoon oregano
1 tablespoon sour cream per serving
