Tangelos

Tangelos are a citrus fruit that is a cross between tangerines and grapefruit. Their skin is vivid reddish-orange, and the fruit is sour, acidic, and juicy. They can be eaten raw or used in salads, desserts, and sauces, and they can be juiced. Tangelos, like most tangerines, have that trademark fat nub on the stem end, so it’s no surprise that they’re related to tangerines. Tangelos (Citrus x tangelo; USDA hardiness zones 9 and 10) are a purposeful or accidental cross between any tangerine and a grapefruit or pomelo (the non-hybrid citrus from which modern grapefruits derive).
