Choose potatoes of the same size. Peel and chop them into 0.5cm cubes. Put them in a pan and cover with cold water.

Add a pinch of salt to the water and bring to the boil.

Drain the potatoes and while they are still hot mash them with a fork and at intervals add the ricotta cheese, the extra virgin olive oil and season with salt.

Mash all the ingredients thoroughly until the mixture is soft and creamy.
