The project would not be complete without at least one copy of the skiving snackbox. This shows up frequently in the books and the movies, and is probably the most famous product they have. The box includes puking pastilles, nosebleed nougat, fainting fancies and fever fudge.
As you can see, the design are based on their early ones, from when their workshop was in their little room at The Burrows, and not the one that you now can find at Weasleys’ wizard Wheezes.
Online I have found recipes for the items inside the box, and I plan to at least try out the Fever Fudge once, and maybe some of the others as well.
