Boiled Beef Tongue

Step 3 Boil

Bring to a boil, and simmer ~3 hours (uncovered) until tongue is tender.

I let mine go for more like 3.5 hours, replenishing the water as necessary and periodically flipping the tongue, then turning the pot off and ignoring it until I was ready to deal with it an hour or so later. The tongue turned frighteningly white while boiling (like any skin when it's waterlogged, I guess) then the exposed bits went brownish as it sat cooling and dried out. It looked a bit too much like an anatomical cross-section, which wasn't encouraging.
