I just now saw this, sorry for the delay in replying! I’m currently in the US and have used a lot of different brands of chocolate, sometimes just depending on what I can find at the store I happen to be at. I’ve used everything from big bars of dark and milk chocolate from Aldi to Ghirardelli to random brands of chocolate chips to Scharffenberger to Lindt other expensive brands from Whole Foods or our local co-op. If you’re looking for a more budget option, the bars of milk and dark from Aldi worked great. If you want more of a splurge, Ghirardelli, Scharffenberger and Lindt are great, too.

At least a couple weeks in the fridge, but they’ll probably last even longer if they’re in a sealed container and kept cold.
