Blender and keep ingredients cold
During electric mixing, precool the knife and container and work only in short pulses, which means that the basil warms up less.
Basil, pine nuts, garlic, Parmesan cheese, pecorino cheese and olive oil are processed without heat. Potatoes, beans and pasta are cooked one after the other in the same water.
Why this recipe works
Pesto Genovese must not be cooked. Heat darkens basil, drives bitter substances out of the olive oil and makes cheese solidify. In a mortar the most traditional texture is created; a blender works if the bowl, knife and ingredients remain cold and pulsed only briefly. Potatoes and beans make the pesto pasta a more complete Ligurian dish.
Recipe
Trofie al pesto Genovese combine rolled pasta with fresh basil pesto, potatoes and green beans to create a Ligurian classic.
Wash basil briefly in cold water only if necessary and pat dry very carefully. Wet leaves dilute the pesto and allow it to darken faster.
Grind garlic in a mortar with a pinch of coarse salt until creamy. Add pine nuts and work into a fine, slightly oily paste.
Grind basil in small portions on the mortar wall with circular movements. Do not roughly crush until a bright green paste is formed.
Mix in both cheeses, then slowly stir in the olive oil until the pesto flows creamy. Cover and refrigerate until used.
Boil a large pot of salted water. Boil potatoes for 5 minutes, then add beans and cook for a further 4 minutes.
Add Trofie to potatoes and beans and cook until al dente according to the package specification. Collect 250 ml of cooking water before draining.
Mix the pesto in a large, unheated bowl with 80 ml cooking water until smooth. Add the pasta, potatoes and beans and mix gently.
Add more cooking water by the spoonful until the pesto coats all ingredients silky. Serve immediately and do not reheat in the pan.
Kitchen know-how
During electric mixing, precool the knife and container and work only in short pulses, which means that the basil warms up less.
Cheese can lump and basil loses colour as well as freshness. Always fold in pesto in a bowl with a little cooking water.
