What's Cookin' is a phone app designed for people who perhaps lose track of what food they already have at home or want to cut down on their food waste. Rather than splashing out on food at the store, why not consider the lonesome leftovers? Or, rather, the possibilities of them. What's Cookin' provides a plentiful amount of recipes that vary depending on what you have at home and brings fun, and maybe experimental, to the kitchen.
