because of the enzymatic qualities of prickly pear juice it is important to freeze it until ready to use. unless you're using it for recipes then anything bigger than a 1/2 gallon jug will go bad before you use it all. but even the fermented juice can be used to make to prickly pear wine!
we also juiced a bunch of apples.
MY PRICKLY PEAR PRODUCTION
if you're using a household juicer it's best to scrape off the prickles. the champion juicers, for instance, only separate the seeds and emulsifies all the pulp. john's juicer on the other hand separates everything, so scraping isn't necessary. be sure to wear gloves or you'll be sorry.
