Translated from Karlos Arguiñano's "Atrévete a cocinar". NOTES: (1) Green beans in Spain are longer and flatter. Once I had them cooked and before I ate them I mistook them for spinach pasta. I would only suggest this recipe if you can get these type of beans, or if you know how to adapt the recipe, because I'm thinking, given their size and shape, that they are prepared and cooked a bit differently than their rounder cousins. (2) When this author refers to a tbsp it means a soup-spoonful. The water was originally described as two tumbler-glasses full.
