Depending on skin color, it will take only minutes of exposure to turn one person beetroot-pink, while another requires hours to experience the slightest change.
To do so, cut off the top four centimeters or so from a beetroot and place it cut-side down in a dish that contains just enough water to keep the cut end under water.
And we had several people tell us that beetroot was a product that people used because of its staining properties and the colour of it, so I thought we'd try out some beetroot as a little bit of rouge.
