A tip of the hat to Belgium ( the new P.B. and J Sandwich)
I first encountered the Belgian made "Lotus Biscoff" cookies as a snack which was provided on the late and lamented airline AIR-TRAN
Other airlines now hand them out (whoopee!) and they are also sold in many U.S. stores. They are good! Probably my all time favourite biscuit.
Lotus also sells a cookie "butter".
I can lose all sense and eat it by the spoonful.
It is also a fabulous alternative to the traditional Peanut Butter and Jelly Sandwich; for those who are allergic to peanuts, and for those who are willing to try a delicious riff on the usual PB and J.
