The most classic way to ripen tomatoes is to tuck them away on the sunniest windowsill in your kitchen. Place the tomatoes stem-side down, which will keep them from rolling and makes them less likely to bruise on the hard surface. After a few days of soaking up the sun, they'll be ripe and ready to enjoy.
