There are times when I don’t have a clue what I am having for dinner, beyond that it is pasta. I choose the noodle type by how much time I have, put the water on to boil, and only then do I decide what the sauce will be.
Note: I deliberately present this dish as a concept, rather than a recipe. Recipes take a long time to follow, and you often don’t have the exact ingredients cited in the recipe. You will make more real-food meals at home if you have concepts stored in your memory, and can work with the ingredients you have on hand.
