Will oranges ripen on the counter at all?
no, they are one of many fruits that must be picked ripe.
Such a bummer I got a bunch of the world's most sour oranges. I think the CSA will give me a refund.
ya try to get a refund. I try them in the store before ordering a case and that almost always works out.
I second the advice that fruit will usually fall off the tree when ripe. Sometimes I can find oranges with no stem(specifically, what can be called the step-base, which I show in my video "How to select fruit in Winter for the ripest, sweetest healthiest
But some citrus doesn't fall even though it's ripe. It gets soft, and it often pulls off of the stem easily.
A ripe orange will be SUGAR sweet. Like someone injected it with sugar.
I rarely eat citrus these days as its so hard to find ripe ones. Thailand is better though as they understand the concept of sweet fruit.
Unripe citrus definitely is harsh on the enamel.
Oranges do ripen off the tree for sure BUT if they have been picked too early, they won't get sweet and are best not eaten.
