This is really the “magic sauce” because it can be adapted for many different dishes – all of them delicious. The basic tomato sauce is a classic that can be served with pasta like spaghetti or linguini to become spaghetti marinara. Or, just add a few ingredients like chopped imported olives and capers, and, presto, you’ll have a spicy topping for firm fish like tuna, halibut or swordfish. Add a few extra flakes of crushed red pepper, a squeeze of anchovy paste and a pinch of oregano and you’ll be the creator of spaghetti alla puttanesca, a notorious dish enjoyed in southern Italy. We make lots of this versatile tomato sauce to store in the fridge because it gives us several dinner options for the rest of the week.
