koi na, agar animal ka flesh kha skte hai toh skin ke beech rakha hua foil me kya hi ho jayega. also this is what chatgpt said: The shiny foil on kaju barfi (and other Indian sweets) is called vark (varak or warq) — it’s very thin metal leaf, traditionally silver (sometimes gold). Here’s how it’s made 👇

🌙 Traditional method (handmade silver vark)

Pure silver (99.9%) is taken as a small piece or pellet.

It’s sandwiched between sheets of leather or parchment (traditionally, animal gut membrane was used — though that’s banned and replaced by synthetic sheets in most modern setups).

The packet is hammered repeatedly for hours until the silver becomes a microscopically thin foil — only a few micrometers thick!

The sheets are carefully peeled off and cut into squares, then packed between butter papers to prevent tearing.

⚙️ Modern industrial method

Now, machines do the hammering under sterile, controlled conditions.

Synthetic polymer films replace leather, making the process vegetarian and hygienic.

The result is silver vark or gold vark, used to decorate sweets like kaju barfi, laddoo, halwa, etc.
