I don't typically buy butter and store it, I only buy as needed and keep it in the fridge inside a ziploc baggie. My mother bought some for me a few weeks ago (she's more of a bulk-buy person) and so I stored it in ziploc in the freezer. I took one out yesterday and had some today on toast. It was icky. It smelled bad. This never happens in the fridge even if I keep it in there for well over a month. Has anyone noticed this with butter in the freezer?
