Chocolate's reputation as a caffeine-crammed, cavity-causing, pimple-promoting, fat-inducing treat has finally turned to mud. In fact the rich creamy substance these days is being touted as an antioxidant that packs a feel-good punch. Scientists are still fine-tuning their theories about phenylethylamine and theobromine (the chemical ingredients that put chocolate consumption on the level of orgasm). So while they're in the lab, you can conduct a little study of your own at Krön Chocolatier. This tiny shop, which spent seventeen years housed in Bal Harbour, has been sweetly ensconced on the second floor of the Aventura Mall for the past two. Chocolate-covered everything -- popcorn, potato chips, Oreos, pretzels, apricots, orange slices, pineapple, strawberries -- is made on the premises. You can mix and match a selection of creams and chews (dark, white, or light) or partake individually of pecan myrtles, rocky road bricks, oversize peanut-butter cups, and Nora's tacos (chocolate shell stuffed with crunchy chocolate, M&Ms, and Rice Krispies). Taste one of Krön's melt-in-your mouth, hand-cut, cocoa-dipped truffles and you'll understand why some addicts claim chocolate is better than sex. The research may be overwhelming, but remember, you're doing it in the name of science.
