Green tomatoes can be force ripened by picking and placing in a PAPER bag with a ripe apple. The apple gives off a gas that will ripen many different type of fruits and veggies. I use it on under-ripe avocados often.

Good tip.

I believe it’s ethylene.

BTW, the very same stuff in apples will also prevent taters from sprouting. So if you have a ten lb bag and use a few and want to keep the rest from sprouting, add an apple in the bag.
