Final answer:
The sure way to ruin meat by tying it to a car is by exposing it to sunlight. Sunlight increases temperature, encouraging bacteria and spoilage. Smoking meat is an effective preservation method that enhances flavor and longevity, beneficial to those needing to extend protein resources.
Step-by-step explanation:
One sure way to ruin meat is to tie an animal to the hood or roof of a car where it is exposed to sunlight. Sunlight can rapidly increase the temperature of the meat, leading to a suitable environment for bacteria to thrive and causing the meat to spoil quickly. Preserving meat through methods like smoking, salting, and drying has been essential, especially in areas like the US South, where the pit BBQ method allowed for cooking large animals rapidly, improving taste, and extending the life of meat. Smoking in particular not only enhances flavor but also prevents spoilage, which is vital for those with limited access to protein sources.
Regarding the preservation of food, methods like smoking and drying, as well as the creation of jams, work by removing moisture and creating an environment that discourages bacterial growth, allowing these foods to be stored without refrigeration. This is why jams and dried meats often do not require refrigeration to prevent spoilage.
