Draw out some of the moisture from the beetroot and potatoes by squeezing the mixture and straining the liquid out. Add salt and cumin.
Heat pan to medium heat. While the pan is heating, form patties with the mixture.
Place patties into the pan and press down so they are flat. Cook for ~3-5 minutes on each side until golden brown. Be careful that they may crumble apart. If they crumble apart, you can press them back together.
Serve on their own, or with some proteins like poached egg or smoked salmon.
