Step one

Boiled Grape Juice (known as “pekmez” ) is a traditional Turkish jam-like mixture that is only made out of grapes. Put a sieve on top of the pot and place the washed grapes on top of the sieve. Squeeze the grapes until all the juice is out, and throw away the rest of the grapes. Put the juice through the sieve again so no pomace is left. Turn on the stove to medium heat and stir until it boils. Keep stirring for one hour while the juice is boiling. The juice will get thicker and sticky. Place the juice into a jar and wait until it cools down. (2 kg of grapes will create half a jar of juice.)

Step two

Place all the ingredients in a pot and stir until there are no clumps left.

Step three

Turn on the stove to medium heat. Continue stirring until the mixture starts to simmer. Slowly reduce the heat of the stove and keep stirring.

Step four

Place the solution onto the oven tray, the layer shouldn’t be very thick.

Step five

Place the tray in the oven for 3 hours at 200F.

Step six

Airdry the bioplastic for 2-3 days.
