In the past year I have purchased lemon curd from Stonewall Kitchen and both times it has gone bad. I emailed them and let them know and they tell me to use it within a month or two of purchase but it doesn't say that on the label. At the same time I have purchased Trader Joe's lemon curd and have not had a proble with it. Anyone else have a problem with Stonewall Kitchen lemon curd? Should I have kept it in the fridge? They haven't even offered me a refund. Thanks!
