Feastworms

In Gasmithon and far Northern borderlands, where trollizards are less viable in the cold, people farm feastworms. These are large, meaty beetle grubs that are raised in canisters. A few adult beetles and a supply of garbage and carrion are sealed inside at the start of the winter and buried deep to keep them warm. In the spring, the canisters are excavated, and the feastworms within are smoked or pickled. Subtle variations of flavor can be achieved by providing different nutrients during incubation.
