Make your own Cranberry Sauce and jelly by growing a couple of cranberry bushes. If you grow Blueberries successfully then you should have good results growing your own cranberries.
They need acid soils so in most parts of the country they are best grown in a large pot of ericaceous compost, watered with rain water and fed with ericaceous plant feed. Alternatively, if you prefer to plant them in the ground, incorporate plenty of ericaceous compost mixed with soil from the planting hole before you backfill with the mixture. Still use ericaceous feed in the spring and summer plus top dress with composted pine needles or similar acidic mulch, once or twice per year. Provided you follow these requirements you will be delighted with the number of berries you will be picking over quite a few weeks
