What are the different methods of ripening tomatoes?

* Place them in a paper bag or even just a bowl with fruit that is already ripe such as bananas, apples and other tomatoes. This allows the ethylene naturally produced by ripe fruit to ripen the others. This is preferable to the artificial ripening done commercially with ethylene which produces fruit that look ripe but are hard inside.

* I pick all my tomatoes just when they begin to change color. They are still green and I take them inside and place them upside down on a beach towel. You can wrap them as green and they will last for up to 3 months before ripening in newspaper. If you place a ripe tomato with unripe ones, they will ripen faster. === ===
