I didn’t realize that there was people out there that didn’t know that tomatoes would ripen on their own if you pick them when they’re green. I mean, I’m a firm believer in the saying “ you don’t know what you don’t know “ - and really why would a person know a thing if they had never been taught it or learned it somewhere else? So I certainly don’t mean to poke fun at anybody for not realizing that, but it was one of those things that I have just known for as long as I can remember because we always have to pick tomatoes when they’re green in our climate.
It stands to reason that a person wouldn’t know what you did with a green tomato if they have a really long growing season and you just don’t pick them off the vine until they’re red! Tomatoes, however, are extremely frost sensitive and our growing season is short. I start my tomatoes in the house well before the snow is gone. Then the beginning of June it’s generally safe to put them outside lol If you don’t have them in a greenhouse, then picking your tomatoes in September while green is normal here. We often get a frost that would kill tomatoes in early September. Some years it’s much later, but if you pick them while they’re still green, they will in fact, ripen in the house.
My mom and grandma always covered them with newspaper. If tomatoes are covered, it is thought that they will ripen a little bit faster and a little bit more evenly. It’s not because they’re in the dark but a low lid or a covering like newspaper actually traps ethylene. Ethylene is a naturally occurring plant hormone in the form of a gas that triggers ripening in tomatoes.
Tomatoes that have reached a larger mature stage that ripen off the vine will be very similar if not the same flavour to tomatoes that are vine ripened. If they have not reached actual maturity before they are harvested they may never develop the same flavour as a vine ripened tomato, which is why they are touted to be the best if you can get them. I find that any ripened inside are still delicious. Most of the ones that ripen inside I use for canning and soups and sauces.
I’m working on processing some more beets today as well as getting the tomatoes that are ripe ready for the canner.
