Heat some olive oil in a pan and then add the meat, apple, and leeks. Add the flour. Let it cook for 5 minutes, turning the meat often.
Add enough red wine to cover the pork. Continue to cook over a low flame. After 2 hours, add the honey, vinegar, black pepper, garum, and spices.
Cook under the same low flame for another 2 or 3 hours, stirring occasionally.
