There is a fabulous Korean spa that my mom religiously goes to in Dallas called King Spa and Sauna. It is an amazing and relaxing place with unbelievable health benefits. We’ve made a monthly date of it with our BFs. They are HOOKED now, too!
“Utilizing ancient Asian treatments, King Spa and Sauna provides the ultimate way to de-stress, relax, rejuvenate and restore your body to health. Made from the earth’s natural elements of soil, salt, stone, wood and crystals combined with heat, allows your body to relax and release toxins enhancing your body’s self-healing abilities.” -from their website
I recommend reading more about it and taking a visit! It’s a really cool experience.They serve deliciously authentic Korean food which includes these hard boiled eggs. The eggs are cooked in an oven within the Fire Sudatorium, the hottest room at the spa. The average temperature is around 180, I believe, and they leave them in there for hours. The longer they are in, the more brown and delicious they become. I usually make at least 8 at a time because J and I will eat 3 each a day when I do. We eat them plain, sprinkled with just a bit of salt, the same way they serve them at the spa, but the uses are endless.
Put as many eggs as you’d like to do onto a rimmed baking sheet and put into a cold oven.
Set the temperature to 190 and bake overnight or for 9-11 hours.
