We're moving out of the Satsuma mandarins and into the Sungolds. They're a little harder to peel, but I love their firm flesh and sweetness. You can tell the difference between the mandarins in your basket and the blood oranges: the mandarins are a little flatter. The oranges are very round. The Moro Blood oranges have a slight red tint on the exterior rind, and of course are quite red and juicy inside. Throw the mandarin in your lunch bag for school or office; save the messy blood orange for your kitchen. Remember the blood orange juice stains.
