I appreciate your research, @martin, and appreciate as much finding that I’m not alone in strongly disliking the particular taste of canned / shelf-stable pineapple juice, at least for cocktails. Trader Joe’s has beautifully packaged pineapple juice cans and they look great on the shelf, but I’d rather toss them in the trash then use them in a mixed drink.
My method for juicing a fresh pineapple works, but it is more laborious than I’d like. I slice off the rind of a pineapple, cut the fruit into chunks, then blend it all into slush. Then I pour that slush into a plastic nut milk bag, and squeeze all of the juice into a bottle with a funnel in the sink. It makes a reasonable quantity of juice, and in my experience the juice tastes quite good for at least a number of days. The plastic nutmilk bag can be washed in the dishwasher and reused.
That said, I don’t love the squeezing process (I always wash my hands extra carefully beforehand, but I STILL find it mildly objectionable that the juice I and others will be drinking is flowing out over my fingers and hands. Maybe that’s just irrational squeamishness, though.)
Looking for a way to make that process easier, I bought this press:
And tried adding the nut milk bag to IT, hoping maybe to get a little more juice from the pulp, too. I found that, first of all, unless you have some surface you can really anchor the press to, like a workbench or wooden counter or something, it’s a real pain to use, because the press itself starts turning once you get it close to being screwed reasonably tightly. So then you have to try to anchor the press with one hand, or with an assistant, while turning it… it’s not fun. And I didn’t find it meaningfully increased the amount of juice I was able to extract from a pineapple.
I was at the boardwalk in Idlewild, New Jersey this summer and saw a vendor using a pineapple corer drill attachment that looked like it made extracting the fruit from the pineapple itself a snap. I haven’t ordered one, yet, but I’m considering giving it a try as a way of making that part of the process a little easier.
Just some thoughts. Seems like there’s not a great replacement for making pineapple juice fresh, and I’m just trying to find ways to make that as painless as possible.
