I’ve searched for chocolate rocks everywhere for a very long time. I used to eat these a lot as a kid and then suddenly they disappeared.

To be honest, there are many brands that make stone shaped chocolate ( 石の形のチョコレート菓子・ストーンチョコ ). The name can vary from chocolate rocks, chocolate pebbles and chocolate stones. I tried looking up the origins of chocolate pebbles but nothing turned up other than the different brands from other countries that sell the same chocolate. I even found a stone shaped chocolate making machine.
Either way, I’m glad I found these in Chicago’s Mitsuwa Marketplace. I haven’t had these in a while.
PRICE
This cost me 99¢ US CENTS!
TASTE
What’s so special about these? Nothing really other than being shaped like pebbles, rocks and stones. They’re essentially like milk chocolate M&M’s. I would say the chocolate tastes semi-sweet and not just milk chocolate.

Would I buy these again? Of course!
I don’t know about anyone else but I love these stone shaped chocolates, regardless of where they come from or the brand. To me, they’re quite delicious and addicting but that’s just me; I love how they actually look like rocks!
