Elderflower liqueur: flowers turning an awful brown! Help!
I'm making elderflower liqueur for the first time. I combined about 20 flower heads' worth of flowers with just under a 750 ml bottle of vodka. The next day, the top layer of flowers turned a dark brown - it looks like they've either oxidized or spoiled. It doesn't seem like the right reaction - at least, not for human consumption. Thoughts? Thank you!
