Fuck’s sake, 2nd time that’s happened to me in this thread. I thought steak should just be beef, but it turns out:

The word steak was written steke in Middle English, and comes from the mid-15th century Scandinavian word steik, related to the Old Norse steikja ‘to roast on a stake’, and so is related to the word stick or stake.

I don’t even want to look up bacon now, I need to believe that it should just be pig.
