I used a clear glass bowl inside this old enamel pot that belonged to my significant others grandmother. This punch is so good and easy to make. Please visit my blog (hennypennyscountrystore.blogspot.com) for the recipe. I also have diced rhubarb fresh frozen in 2 lb. packs for sale in the shop. I have rhubarb punch made to sample in the shop this weekend, June 26 & 27, and next July 3 & 4. Hope y' all can come by and visit.
