When I was in grade school, I commandeered a shelf in our refrigerator for a science experiment involving pineapple and... something else, I can't remember what. The something made the pineapple bubble and ooze up over its dish, and as I recall, that meant the experiment was a success. My mother forgave me, eventually, after making me scrub the inside of the fridge, and for many years I stayed clear of pineapple, but now I love it. (Do you know how to choose a ripe pineapple? First, smell. It should have a strong pineapple aroma. Second, gently tug on one of the inner leaves. It should pull out easily. Third, the fruit should feel heavy for its size.) We're grilling pretty much everything these days, so I glazed ripe pineapple rings with a simple maple-chipotle sauce, and tossed them on my panini press. Sweetness made even sweeter. A scoop of vanilla frozen yogurt would be the perfect topper.
