Blood oranges are oranges with a high level of anthocyanin which gives them a crimson hue. A natural mutation of a regular sweet orange brought about this beautiful variety with a taste that's a cross between an orange and raspberry, and tarter than a sweet navel orange. Cool-weather helps promote the production of anthocyanin, so the best growing season is between December and May. Grab some when they're in season, and squeeze the juice to keep in the freezer for a quick margarita fix! Blood oranges are gorgeous in salads, orange curd, and cocktails! Their deep color makes for an exquisite presentation!
