I am doing Christmas dinner for my family this year and made my cranberry sauce this evening (trying to get as much as possible done in advance). It seemed to have a really bitter aftertaste - I know that cranberries are sour, but this didn't seem quite right. I am wondering if I have fecked up by putting in orange zest/a few cloves/cinnamon, though can't see how any of these things would make it bitter unless it's a stray orange pip or something. Otherwise it's just cranberries, water, sugar and orange juice. Do I have to start again or does that sound about right? Or should I just get them all pissed on mulled wine when they get here and hope they don't notice?
