Bounties attract serious brainpower to the challenge.
Peanut Butter and Jelly sandwiches are a favourite among a large proportion of the American population, so much so that April 2nd each year is celebrated as National Peanut Butter and Jelly Day in the U.S. Despite its popularity in the U.S. and worldwide, there has been little innovation around ease of peanut butter application on sandwiches (other than a controversial few! Check this out). The task of digging a spoon into the peanut butter and jam jars and then spreading them on the bread is pretty tedious and messy.
I thought of a more convenient alternative to the existing application technique:
Peanut butter and jelly slices! We can make peanut butter and jelly slices by simply taking transparent edible wrappers (made of casein protein from milk) and applying a layer of peanut butter or jam on them and sealing them (this is in contrast to re-engineering the peanut butter formula to be moldable into slices). This can be replicated in factories with the help of automation tools making the process of manufacturing these very scalable. If similar to cheese slices (but improved) we could just buy peanut butter and jelly slices off supermarket shelves, it would make the job of putting together a peanut butter & jelly sandwich (take 2 pieces of bread and place any number of peanut butter, jam and cheese slices between them) as easy as opening a box of ready to eat stuff.
Casein films used as edible wrapper
The idea can be further expanded to include different combinations like peanut butter, jelly, jam and cheese slices sold separately or packaged together two at a time. The consumers could buy based on their preference.
Further scope for innovation could be flavored edible wrappers to add another dimension of customization. This could be a time saver for all the messy cooks around the world!
