Even their tongues were used for consumption
You should know by now that the people in the colonies tried to use every bit of an animal once they killed it. That includes, of course, its tongue. There were no exceptions; if it had a tongue, they were going to cook it. After all, it is a muscle.
There were plenty of methods to cook this meat. People would roast it, boil it, or fry it. It depended pretty much on what was more popular in your area and how fast did you want your food. Even nowadays, tongues are still sold in many parts of the world, although they are mostly from cattle.
