Sandwich in a can goes on sale

Candwich, a sandwich in a can, is now available to buy in the US and online.

The product was invented in the US by Markonefoods and has a shelf life of a year.

It can be dispensed by vending machines and you can buy a four-pack online for US$12. It costs $72 for a pack of 24 cans.

Candwich will eventually be available in a range of flavours including US-style peanut butter and grape jelly, barbeque chicken and pepperoni pizza.

The peanut butter and grape jelly version requires diners to spread sachets of the filling on to the bread but the rest have the fillings baked inside, like a pasty.

Creator Mark Kirkland, from Markonefoods, said: “My original idea was to stack cookies in a soft drink can to sell in soft drink vending machines. I started looking for a technology for shelf stable sandwiches, which I wanted because it was a healthy and convenient meal.”

The product’s long shelf life is achieved by controlling pH, oxygen and water levels in the packaging.
