Pure-Cote B790 is often used to create clear, flexible films and glasses from liquids. It's a less used modernist ingredient but still very useful in certain applications.
We always recommend ModernistPantry.com, they have great service and are really good to work with (because of this, we do have an affiliate relationship with them. We also recommend purchasing from WillPowder.
When making a film, you will typically use 10-15% of Pure-Cote B790.
Pure-Cote B790 can be dispersed at hot or cold temperatures and sets quickly at room temperature.
Take 200 grams of a flavored liquid, place in a blender, and blend in 24 grams Pure-Cote B790. Take a large spoonful of the liquid and pour it onto an acetate sheet, evenly coating it.
Leave the sheet out to dry at room temperature for several hours, or preferably overnight. Once it has dried you can take pieces of the "glass" and use them as garnishes on dishes.
For an even crisper texture you can dehydrate the dried pieces of glass for several hours.
