Chandi Varak is a edible foil made of pure elemental silver and is used for garnishing a variety of Indian sweets such as burfi etc. The silver is edible, looks attractive though it’s flavorless.
Vark is made by pounding silver into a thin sheet a few micrometres thick. It is backed with paper and peeled before use. It is extremely brittle and breaks into smaller pieces if touched. Vark sheets are laid or rolled over Indian “sweets” also known as “mithai”
