Carambola fruits are ovate to ellipsoid, 2-1/2 to 5 inches (6 to 13 cm) in length, with 5 (rarely 4 or 6) prominent longitudinal ribs. Slices cut in cross-section are star shaped. The skin is thin, light to dark yellow and smooth with a waxy cuticle. The flesh is light yellow to yellow, translucent, crisp and very juicy, without fiber. The fruit has a more or less oxalic acid odor and the flavor ranges from very sour to mildly sweet. The so-called sweet types rarely have more than 4% sugar. There may be up to 12 flat, thin brown seeds 1/4 – 1/2 inch long or none at all. Seeds lose viability in a few days after removal from fruit.
