Think Mumbai, think hot Vada Pav

One of my favourite things to eat in Mumbai is the Vada pav. It was an invention in 1966 of a man called Ashok Vaidya (pic. below), who had a stall outside Dadar railway station. It started as a quick, cheap and filling snack for Mumbai’s local train commuters. Vaidya passed away some years ago, but his invention lives on, moving outside its home town and spreading across the nation.

It is a laughably simple dish, just a vada (that’s mashed potato and spices covered with batter and fried in oil) placed between bread, served with a fried chilly and optional chutney. Pav is the Marathi word for bread, derived from the Portugese word for bread, Pao.

From streetside pushcarts the vada pav has moved into expensive restaurants where it is served with expensive crockery and cutlery, care for aesthetics, and a variety of accessories to eat. There are even food stall chains selling branded vada pav across the country. However, my tastiest mental image is of it being served on a newspaper with a fried green chilly, from a pushcart.
