Yeppers, the deep burgundy knobs on top of Prickly pears that develop in the fall are the source of a fantastic tasting juice that has been associated with numerous health benefits. It is apparently much better known for its exquisite taste in Italy and France than in the US (excluding some in Southwestern states). Be forewarned the pursuit of the tunas (that's the name of the fruit) is fraught with spiny obstacles - the cactus pads have LARGE NEEDLE_LIKE SPINES & the fruits have deceptive little bumps that are composed of tiny hair-like spines just a few millimeters long that work into the fingers of the unwary - must go prepared & protected. After several harvesting forays I have concluded the thick latex dish washing gloves that go midway up my forearm seem to afford the best protection. But it is worth it! The juice is mildly astringent with an initial taste reminiscent of raspberries and blueberries and an aftertaste that is delicately floral, not unlike the floral essence of rambutans. The beautiful magenta jelly has prompted all tasters to tentatively savor the initial dab & immediately dig in for more! Have your jars washed & waiting in simmering hot water bath before starting & put lids in to simmer when bringing strained juice to a boil. Note - prep time does not include stalking the fruit! We are lucky because the condos across the street use these for landscaping and it takes less than 10 minutes to harvest a colander full!
