A happy side effect came from the bromelain, an enzyme that decreases inflammation. People often notice relief from joint pain and arthritis when taking bromelain, and that was true for me too. I also noticed another side effect in the easing of gastro-intestinal symptoms I've been working on through diet. The core has more bromelain than the fleshy fruit portion, and it seems like there has to be a way to preserve them.
I have chopped up a couple of cores and have them soaking in vodka. Pulling a slice out one evening in an attempt to stave off stomach problems worked, but woo boy - very potent to chew.
Today I decided to dry the core in the oven.
They went into the oven on the lowest setting (Warm) and I left to do some work for a few hours.
When I returned, they were done.
They taste just like small pieces of pineapple flavored candy.
Never again will a pineapple core go to waste! These would be worth drying even if it was just for the deliciousness, never mind the health benefits.
