What are alternate uses for leftover buttermilk? [closed]

Buttermilk is one of those pantry items that I buy for a specific recipe, then don't know what to do with the leftovers (and I think this is not uncommon). In my question about buttermilk in soda bread, the topic of alternate uses came up in the comments. I'd like to make a list of these uses. Here's what I have so far:

pancakes (instead of milk or yogourt)
quick breads, scones (instead of milk)
cakes
mashed potatoes (instead of milk)
low-fat muffins (replacement for oil)

(Note: This should be a community wiki item, rather than a question, but I'm not sure how to flag that.)
