which one has no burnt alot?
ok wht i would do is make the box and lid from stirefome put a little sodust on the botem then put ice on the saw dust them put sawdust over it and put the real cube of ice on the second layer of sawdust put the lid on and go
put an ice cube in a bowl with other ice cubes
I'm not sure how to construct something but I do know that in the old days before freezers, people use to pack the ice houses (which were just sheds) with ice and then pack saw dust all around the ice so they would have ice all through the summer and it supposedly kept the ice blocks frozen for months of above freezing weathermaybe do some kind of research into how they maintained their iceGood luck on your project.
The best thing to use is Parchment Paper-cookies don't stick or burn on it, and the sheet is reusable for the next batchIt can be found in the same section as foil,saran wrap and wax paperHonestly-I have been baking for 46 yrsand it is the best!
