You see this most often in high-quality pinks (like Brandywine) and dark beefsteaks (like Cherokee Purple). Instead of being slick, mushy, or watery, the flesh is made up of thousands of tiny, distinct juice cells that sparkle in the sunlight and give the tomato an incredibly rich, melt-in-your-mouth texture!<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\ud83d\udccc Quick Summary (TL;DR): Zvart Heil Lekken \ud83c\udf0d Origin: A rare dark heirloom.
