| Pasta, amount, and cooking | 320g spaghetti (serves 4) | 300g fettuccine | Half a pound of square spaghetti (per serving, can be doubled) | 1.7mm spaghettini | 80g spaghetti | 160g spaghetti/linguine/penne (serves 2) |
| Handling of garlic | 3 whole peeled cloves; scent the oil, then remove | 2 crushed cloves; cooked without browning, with splashes of water | 4 cloves, thinly sliced; deliberately extra for toastiness | Peeled, cored, then finely chopped in a crushing motion. About 10g | 1 clove, sliced (crushing or mincing also noted as fine) | Crushed with skin on, just to scent the oil, then removed |
| Use of chili | 2 dried chilies, chopped | 2 chilies (fresh or dried), finely cut | 1 tbsp chopped Calabrian chili | Chopped with seeds in and crushed together with the garlic (adjust heat to taste) | 1, heated from cold together with the oil in the pan | None — pepperiness comes from black pepper instead |
| Timing of adding anchovies | 25g, sautéed with the garlic and chili over medium heat for 5 minutes until dissolved | 6 fillets, melted into the oil over low heat with a little water added as needed | 3 fillets (can go up to 8-10 for more, lightly chopped) | Not sautéed — melted into the sauce after the tomato has reduced | 1 fillet, added once the garlic has turned golden | 3 fillets, sautéed for 1 minute and melted in |
| Type and prep of olives | 100g pitted Gaeta olives, broken up and added in the back half of the sauce | 3 tbsp Kalamata olives, hand-crushed to release their juice before adding | About 5 Castelvetrano olives, pitted and finely chopped | Pitted and crushed, sautéed in oil first alongside the capers | About 4, torn by hand (slicing also fine) | 10 Kalamata olives, sliced and added |
| Prep of capers | 10g salted capers, rinsed and roughly chopped | 2 tbsp salted capers, well rinsed | 2 tbsp, chopped along with the olives | Added to the oil at the same time as the olives to bring out their aroma | 5g, added at the same time as the anchovy and semi-dried tomato | 1 tbsp, chopped and added |
| Type and amount of tomato | 800g canned peeled whole tomatoes, lightly crushed, simmered 10 minutes | 400g canned peeled tomatoes, crushed with a masher and added | Half a can of Mutti cherry tomatoes | Whole peeled tomatoes, added whole and left coarse rather than fully crushed | 90g homemade tomato sauce plus semi-dried tomatoes (no fresh canned-tomato cooking on the day) | 35 grape tomatoes, halved and used (no canned tomato) |
| Finish | Chopped parsley only; no cheese or breadcrumbs | Plenty of parsley, plus an extra drizzle of olive oil | Deglazed with lemon juice; breadcrumbs, basil, and Parmigiano added | No added salt — relies on the sauce's own saltiness, plus the pasta water for emulsion | Italian parsley and a finishing drizzle of oil, dried oregano optional | Just black pepper and chopped parsley; no cheese |
