Sauces make our food delicious, moist and exciting. Small sauce packaging not. Please, meet IKURA - sauce caviar - sauce delivery right into your mouth avoiding naughty sachet and plastic containers.
How does it work?
Sauce, for example, soya sauce is spheriphicated ( enclosed into the small 2-3 mm sphere of edible material such as sodium alginate/agar-agar/starch/gelatin).
Soya sauce spheres incorporated into the product during preparation - mixed with rice when sushi is made.
When you eat your sushi sauce bubbles popped while you chew. You get your sauce. You get new gastronomy experience and no waste! Your hands are clean, no extra action - perfect for on the go.
Other sauces such as ketchup/mayonnaise can be enclosed in bubbles and served with chips. Hummus/guacamole can be enclosed in larger bubbles to avoid plastic packaging/ peel offs altogether.
All suggested substances are edible and easily sourced/available. Spherification is a proven method widely used in the pharma and food industry. https://en.wikipedia.org/wiki/Spherification
Shperiphication can be design done by a robot in the presence of the customers as advertisement/ entertainment feature.
Using algae products in the light of developing 3D ocean farming is very perspective as locally sourced raw materials lower the price, create local jobs and reduce carbon footprint.
Try it, it's fun!
