When Claire and I were young we used to make these potatoes after the pub. Many a young man loved us for our spuds and we were often paid in pints.
Now I often eat them in Hare Krishna Higher Taste with my friends Kat. Together we have learnt to pile our food perfectly. These spuds are very similar to the ones we put on top of our rice.
I have been making them for over 20 years so please excuse the vagueness and alter to your tastes. They originate from a Madhur Jefferies recipe which also had cauliflower.
