To ripen green tomatoes, place them in a box with newspapers. Wrap each tomato in newspaper to prevent them from touching each other.
You can replicate the box method using a paper bag if you have just a few tomatoes. The brown paper bag will create a warm, humid environment to help the tomatoes ripen.
To ripen green tomatoes, place them in a warm, sunny spot indoors, preferably on a windowsill or south-facing window. The warmth, rather than direct sunlight, facilitates ripening.
