I am familiar with hanging/stretching meat to improve quality, but I have to admit leaving the guts in is a new one on me too.
I can also name you some fish that gets the guts left in
Here's a nice read
Witness to a Hanging
Occasionally I have the opportunity to enjoy the company of San Antonians Bill and Pam Shown, who spend some of their getaway time in my hometown of Marathon. Bill is an avid dove hunter as well as an artist on the BBQ grill. One evening, I was invited over to their rental cottage, where Bill was busy with shish kebobs. The ’bobs were stacked with chunks of red onion, bell pepper, tomatoes and medallions of what I assumed to be filet mignon. The meat was of a deliciously dark red color and a deep rich flavor that rivaled some of the choicest cuts of beef I had ever tasted. Once I polished off more than my share of skewers, our discussion turned to the onset of the west Texas dove hunting season. In passing, I mentioned my reservations when it came to the taste of dove meat.
“You didn’t like the kebobs?” Bill asked.
“Of course I did,” I replied. “Who doesn’t like beef fillets!”
“Those weren’t beef fillets,” Bill explained. “They were white-wing dove breasts.”
Jaws agape, I made my way back to the grill and filled my open mouth with another helping.
Bill swears by his dove-aging routine and says he has aged the little game birds the same way for the last 20 years using the following technique: Immediately after retrieving his downed birds, he stores them in his game bag. Once he’s hit his limit, Bill loads his birds into a gallon-sized zip-lock baggie (a gallon-sized baggie holds exactly one limit of birds) and pitches the baggie into the ice chest. While everyone else on the day’s shoot is busy cleaning their birds, Bill relaxes with a refreshment and Topo Chico, shaken not stirred. (Bills says the bubbles in Topo Chico, a mineral water from Mexico, are strong enough to clean your teeth.) Once Bill returns home, he marks the baggie with the day’s date and throws the bag of birds — heads and feathers and guts intact — into the back of the refrigerator, where they stay for up to two weeks. Sometime during or slightly before day 14, Bill spreads a newspaper out on the coffee table, turns on his favorite sports channel, and proceeds to pick, snip and gut the birds, then washes them, cooks a few for dinner and stuffs the rest into quart-sized zip-lock baggies (eight per bag is a perfect fit). Then he fills the bags with water, seals them and pops them into the freezer. While biologists and health professionals might blanch at Bill’s brazen disregard for meat processing standards, they would be hard pressed to argue with his culinary results.
Aging and hanging game may not be for everyone. For many, a fondness for game continues to be an acquired taste and aging it, while increasing tenderness, may also tend to pump up an already robust flavor. But for those who manage to fill their larders each year with nature’s offerings, hanging and aging game may be another way to make good fresh food taste great. And for the generation of Texas hunters like me who are beginning to feel their years add up, extolling the benefits of aging game might be the only opportunity to discover something positive about watching meat grow old.
Meat Safety Guidelines
Aging game meat considered “red,” such as venison, duck, elk and dove, has its benefits. However, it is usually recommended to avoid aging any “white” meat, such as quail and turkey.
Safe game aging depends upon storing carcasses or cuts at a temperature range between 34 and 37 degrees. Higher temperatures will encourage spoilage and lower temperatures will simply freeze the meat and halt the aging process. For example, keeping meat at a temperature above 40 degrees is a recipe for gastronomical disaster, but freezing the game quickly will cause “cold shortening,” and the meat will become tough. Ideally, meat should be chilled to just above freezing and then held at that consistent temperature for a duration determined by the meat’s species. At 34 degrees, deer, elk cows and moose cows should age for a minimum of seven days. Bull elk and bull moose may require twice as long. Antelope should be aged for only three days, as the structure of antelope meat tends to collapse quickly.
Once aging is complete, be sure to remove any surface fat. Also, look for and trim off any slime due to bacteria and mold growth, especially on lean meat.
Aging meat that has no surface fat at all is not recommended. The lack of fat allows the meat to lose moisture and is likely to encourage deterioration.
It is often advised not to butcher or process game while it is in rigor mortis.
Pork should not be aged. Unsaturated fats in pork meat tend to oxidize, adding a rancid flavor to your chops.
If ground meat or sausage is the final destination of the season’s kill, then aging is not really necessary. The term “freshly ground” applies to the process as well as the flavor.
It is often suggested that removing the crop of a game bird immediately after downing the bird will prevent the meat from souring. The crop, filled with grain, has a tendency to ferment.
Fish-eating ducks may need additional soaking or marinating in acidic mixtures once aged.
A final rule of thumb when aging: If the meat is emitting an unpleasant odor, then throw it away regardless of the amount of time and care spent on processing and aging your game. Recognizing a bad smell is an important tool in the culinary skill set used for preparing wild game.
