So the last bar I purchased for the car ride home was Theo's 70% Sea Salt bar. I got this mostly for my lovely chauffeur, as sea salt is not my favorite thing in the world, but we did not get to it the whole drive. I wound up breaking into it at my brother's house the following night.
This bar is very good. It's simple and exactly what you'd expect. Sea salt has a tendency to dominate whatever its been added to, but Theo is an excellent chocolate company, and they smartly worked hard to make sure the flavors balanced.
One thing I very much like about Theo is that they don't try do too much. And this is a great example of it. They make good quality chocolate, and if you want something added to it, they'll do it in a tasteful way.
All this said, every time I see Theo sold, and I can't find their 90% Venezuela-origin bar, I cry a little on the inside.
(As a side note, Theo is based in Seattle, and their factory building was shared with a band/actual circus I loved very much called Circus Contraption.)
Bottom Line: If you are looking for a high quality, well balanced sea salt bar, this is a nice starting point.
