" Trifolate orange: As food
The fruits are very bitter, due in part to their poncirin content. Most people consider them inedible fresh, but they can be made into marmalade.[8] When dried and powdered, they can be used as a condiment."
Note that like some locust trees they have thorns!
Thanks.
Yeah, I figured they wouldn’t be very tasty and would need further treatment.
But would sure make my neighbors go... “WTF?”!
Interesting thing I also never knew is that the tasty Damson Plums are very cold hardy. I’ve just grown the American plum here which comes through every year. But is only good for jelly and jams.
