I have a large tree full of Surinam cherries. They are starting to drop (ripe) and would love to make something with them. We eat them plain and with sugar on crackers. I know they are not in everyone's garden and if you have eaten a not fully ripe one it can turn you off of them, but they are really good when ripe.
Surinam cherries and loquats were fruits my friends and I used to poach from the neighbors yards when we were kids. Both had big seeds and were perfect for seed spitting wars : )
