‘Mystery Keeper’ is a rare tomato that was listed in Seed Savers Exchange in 2010 by David Kent of Mt. Shasta, Canada. The ‘mystery’ in these tomatoes is that they ripen incredibly slowly, and the inside will be ripe before the outside turns from yellow to a pinkish blush.
Smooth, round, medium-sized, yellow with a pink blush and deep pink flesh tomatoes are produced by robust and vigorous vines with regular leaf foliage. The fruit has dense, acidic flesh that is excellent for making fresh salsa. Tomatoes harvested in the fall when they are yellow to light green continue to ripen indoors throughout the winter. This variety must be felt for softness to the touch to determine ripeness. You can store them at room temperature without sacrificing fruit quality, and they will slowly ripen until long after the season has ended. Good disease resistance. Late season, after 90 days.
