Okay, so I'm slightly over-excited by this, but Tesco finest mince pies don't have palm oil in them! Their normal ones do though, ditto with Sainbo's, their TTD ones are palm oil free while their normal ones aren't. About bloody time! I haven't had a good mince pie for years. (I found this out today when I mooched up to Tesco and bought three boxes on a 3 for 2 offer as I was indeed over-excited.)
Other places I know that have such a marvel are Waitrose, Co-Op and Iceland. Haven't tried the ones from Iceland yet and we don't have a Co-Op where I live. Dunno about Aldi or Lidl, M&S mince pies do contain palm oil, the bastards!
