If an Orange is slightly green, is it safe to eat?!
Answers:
yes . . it's possible they're not quite ripe . . but oranges don't have to be totally orange to be ripe.
If it's sour . . then don't bother . . but my guess you'll be pleasantly surprised. Oranges oddly enough can sit on a tree for months in a ripe condition. . .you can have next seasons crop starting and last season't growth still on branches.
The skin starts off green and as it ripens . . it's mature color comes out . . Lemons start out green, so do grapefruit, tangerines and the rest
Yes, its just the colour hasn't changed. it may be very slightly underripe but still OK to eat as long as you don't mind it slightly sharper than usual.
