Wandering around Williamsburg last week, my nose (or “schnozz,” if you prefer) led me down a street to a place that looked like a warehouse. The warehouse was actually home to Mast Brothers chocolate, one of the most revered chocolate companies in the country. You may recognize their chocolate bars as the ones with wrapping so pretty, you want to wallpaper your house with them. Also their bars are the ones so expensive, you won’t be able to put your children through college if you buy one. Turns out all their chocolate is made right here in this spot where I was standing. Naturally, I went inside.
