The bitter bite with the subtle sweetness is IMHO the perfect combo. Add some coarse salt, crunch and dried berries and then you’ve got me hooked.
I’ve started making my own chocolate back a couple of years ago.
I wanted a chocolate bark with salt and almond and goji berries and hemp seeds. Yes, all of these things in one bark and (obviously) no mass market brand made it so I made my own. Easy.
