Pears are in their prime during early winter. Here are some tips to make them taste their best:.Pears ripen very effectively at room temperature over the course of 4 to 7 days.If you want them to ripen even faster, add some apples or bananas to the mix.The extra fruit will increase the amount of ethylene, the gas that helps with ripening.For even more speed, to ripen in 2 to 4 days, place pears in a paper bag, and close the top to trap the ethylene gas.The paper will breathe enough to prevent mold but will still capture the gas to create a ripening chamber. .Add an apple or banana to the bag to achieve the fastest ripening process possible
