Yum, chocolate: is there any substance more synonymous with willful self-indulgence? Yet recent studies have shown it has health effects – and thanks to John and Kira Doyle, now it also has positive social ramifications.

John & Kira's is a Pennsylvania-based company that manufatures high-end chocolates. But instead of a fussily-decorated cardboard, these arrive in a simple pine box adorned with the loveliest of bows, stamped and sealed with wax.

The taste isn't traditional, but surprising and fresh.
