Question: how to cook a small whole pig?
Answer: In order to do this, the best method is to start low-and-slow—a 275°F to 300°F oven is ideal—and roast until the pig is cooked to at least 160°F in its deepest joint (the shoulder joint close to the head). This should take around four hours for a 20-pound pig, more or less if the pig is bigger or smaller.
