Today I found out that you can get a consumer/at-home version of these rocks to use on your own! They are made a company called Hot Rock (Rok Bistro gets the commercial version of these from there, too). As the website says:
Discover the speed, ease, sensational taste, uniqueness and healthy aspects of Hot Rock meals. Any meat tastes better when cooked on a Hot Rock. Cater to the health conscious by creating low-fat, low-carb meals with “sizzle.“ Amaze your family and guests with fun, festive, and delicious meals they will never forget. Preparation time is minimal. Simply heat a rock for several minutes on the stove and take it to the table where the diner grills their own meat on a volcanic rock—an unbelievable experience. Side dishes can be prepared in advance or simply purchased ready-made from your local delicatessen. Preparing and enjoying meals has never been easier or more fun. Hot Rock gets hotter and retains its heat longer than other products and does not require messy or dangerous heating sources at the table. The rock maintains effective cooking temperature for approximately 25 minutes.
Hot Rock is the perfect solution for …..
- Health conscious diners who don’t want to sacrifice time, taste or quality
- People who entertain but don’t have time to prepare fancy meals
- People on the go who don’t have time to cook
- Children who complain about dinner—they won’t complain about Hot Rock!
- Year round dining—Hot Rock can be served in the dining room or on the patio The home, office or dormitory—all you need is a Hot Rock cooking set and portable stovetop
Not related to the volcanic rock components, but I love chocolate and have to share: we concluded the meal with a to-die-for dark chocolate coconut almond dessert fondue with lots of little treats to dip. It was spectacular! We had a great time, and hadn't eaten outside of the house for 10 days to save money, so this was a real treat!
