You can use guelder rose berries to make something similar to cranberry sauce, or cooked in jam/puddings/etc mixed with other fruit and enough sugar to take the edge off their tartness.
Autumn olive (elaeagnus umbellata) is another red berry to look out for around now, the fruit are quite sharp but sweet enough to eat raw.
