Yes, I did it for first graders. It was loads of fun. I had the kids read the story and brain storm the recipe. I brought the "stone" that I had found at a store that had washed and polished stones. Then I washed the stone with soap and water in front of the kids so everyone knew the stone was clean. I also brought the spices. Have some kids bring things like bread and butter to go with the soup if you want. Part of the fun was to have the kids bring fresh vegetables and have them cut and slice them but then you need lots of adult help.
Then we cooked the soup. It was great and everyone had fun.
