Found some purple sweet potatoes at the grocery store the other day so I wanted to do something cool with them. I also recently got a dehydrator so had to put that to use :p This purple sweet potato powder is super easy to make and mostly involves inactive cooking. Once you've blitzed it up, store it in a cool dry place for up to a month. Use it for plating, as a natural purple food colouring in pasta and bread doughs, as a colourant in desserts, creams, fillings, icings, ice creams etc. I used small stokes purple sweet potatoes but if you can somehow get your hands on ube the same technique would work.
