I won't bore you with a standard french fry and hamburger recipe- I'm sure you can figure that part out for yourselves : )
French Fries (fresh or frozen will work)
Wilton Edible Adhesive
Any desired garnishes (cheese, condiments, veggies, pickles, etc)
Note: You can find the Wilton Edible Adhesive in any craft store, such as Joanne's Fabrics or Michael's. It is normally used for decorating wedding cakes, so it can be found in the cake decorating aisle. It costs about $6-7 bucks and can be used for lots of other edible projects - pic below!
Assemble the buns first. I have done this twice, once with fresh french fries and once with frozen. The only discernible difference was that the fresh potatoes glued together more readily, probably because they were not as wet. However, I did like using the frozen fries because I had more options for shapes & sizes to glue together. If you don't usually make homemade french fries at home, now would be the time to give it a try! They taste infinitely better than the frozen ones you're used to eating (and that most restaurants are serving you!)
Heat the oil that you plan to fry your french fries in to 400 degrees, or preheat an oven to 450 degrees if you plan to bake them. Begin by assembling the puzzle of your bun, using longer and shorter pieces to achieve the desired shape. Then separate them and glue them in the order you assembled them in. Allow to dry for about 5 minutes, then fry or bake your french fry buns.
If frying, use a large pair of tongs or metal spatula to carefully remove them from the oil to drain. If any pieces fall off, don't freak out! The glue has no flavor or texture and you can easily reglue the piece without any noticeable difference to the food.
Finally, make your burgers, add your desired toppings, and enjoy!
