I normally freeze them when they're still yellow (those that I don't eat first). Last time I hung them up to darken and develop sweetness, the autumn was quite wet and humid, and some of them went mouldy.

If you freeze them when they're yellow and leave for a little while, they still go brown but don't develop as much sweetness - good for a diabetic like myself. I first wash them and remove the stones. I always have enough in the freezer to give me a year's worth of sticky toffee pudding and date & walnut cake.
Unfortunately my Spanish friend has moved houses and no longer has a date palm, so next year I'll have to do what Margaret calls 'rural shopping'.
