As far as fleur de sel chocolate caramels go, Fran’s is a great staple. Barlovento packs the biggest caramel chew (a big hunk of chewy caramel with a thin coat of dark chocolate) and most salt (high points for the latter). Poco Dolce has the most sparing smattering of salt, but, in my opinion, the highest quality chocolate taste. Poco Dolce is a small crispy center of caramel toffee and a solid sea of dark chocolate surrounding it.
Bonus: Poco Dolce has a large variety of flavors all topped with sea salt. YUM
