Elderberry muffins

Hmmm picked some elderberries yesterday and made some muffins. They're coloured very dark. They don't taste of much. I was a bit nervous baking with them because of the reputation of elderberries to be poisonous so I boiled them up before putting them in the mix. Don't think this was a good idea as all the sweet and sour tastes all mingled together to create bland. The seeds are rather crunchy like raspberries but that doesn't really bother me.
