Recipe first for 4 people based on Spinach - cooking method to boil.

Preparation:

Preparation: I clean some fresh spinach leaves well. I peel a medium potato. I put the spinach and the potato in a saucepan with cold water (about a third of a litre) and let it boil for about 30-45 minutes. Halfway through cooking, add a spoonful of cornstarch and a pinch of salt. When it's cooked, I remove it from the heat, let it cool and pass it to the food processor. I add a teaspoon of extra virgin olive oil and mix.
