Whenever I use mixed game as dice for a stew or as meat to be minced, I look to the tough cuts that have more flavour and take longer to cook. We call these the second-class cuts. To cook second-class cuts, you need second-class methods that break down the connective tissue, such as braising, boiling and stewing.
All these methods work on a long, slow and low-temperature principle that breaks down the sinew, turning it to jelly. This makes tough meat more digestible and helps it to remain moist. Mincing also tenderises the meat by breaking it up and allowing it to cook more quickly, retaining the flavour and again not allowing it to go dry. People do not see duck, pheasant or even rabbit or hare as having second-class and first-class cuts, but they do.
As with breast meat of gamebirds, the loin is tender and needs very little cooking. Using long, slow, second-class methods to cook this will make it dry and tough. This is a common mistake — cooking first-class cuts too long and second-class not long enough. We are too used to looking at a chicken or a hutch rabbit and cooking it with no regard to the time needed to cook different pieces. That’s because these are young, intensively farmed animals that do not move around much. They are tender all-round and lack the flavour of older animals.
The secret is recognising that game is different and understanding which parts need more cooking and which parts are more tender so need less cooking. Once you understand this, you can work out which part of the animal will work for the recipe you want to recreate. During the season, I normally prepare all the game and freeze the breasts separate from the legs. This gives me direct access to what I want for a particular recipe.
For this game meatballs recipe, I am using pheasant, partridge and rabbit legs that I have minced once. Mincing once gives a more meaty meatball, but if the preference is for a smoother texture, then mince the meat twice to break it up a bit more.
