Example: I recently attempted to grill duck legs on my propane Webber. I was afraid of flare-ups due to the high fat content in the duck meat so I grilled with somewhat low and indirect heat. It took a long time, but I got them looking lovely and brown and not burned. The only problem was this: they were tough and didn't taste very good at all. Clearly I did something very wrong. Any advice?

Problem: I've been looking for a soda bread recipe to try and I notice that most of them contain buttermilk. Buttermilk is not a standard part of my pantry. Part of the appeal of soda bread is that it's quick to throw together, so having to go shopping for a specific ingredient interferes with the spontaneous aspect. I know there are lots of substitutions for buttermilk (using a bit of lemon juice in regular milk is the one I usually use), but I'm wondering what it is about buttermilk specifically that seems to be a standard part of soda bread. Is it just traditional? Or will it add a particularly noticeable flavour/texture?Edited to add: I know that its functional purpose is to provide an acid to react with the soda for rising; so is it just that it used to be the most convenient acid?
Solution: Why does soda bread call for buttermilk?
