Tips
Use the heat gently
Anchovies melt quickly and can become bitter if the heat is too high. Keep the pan on a gentle heat to draw out a soft savoury flavour.
Build the sauce with pasta water
Seasoning should come mainly from the pasta water. Since anchovies are naturally salty it is best to keep the pasta water lightly seasoned.
Emulsify with movement
Shake the pan or use a gentle tossing motion to help the starch blend with the butter and anchovies. This creates a glossy and well balanced sauce.
Remove the garlic before mantecare
Once the garlic has released its flavour take it out so the final sauce tastes clean and smooth.
Use a spatula
Use a spatula to scrape around the edges and the bottom of the pan to build flavor.
Boiling water
At the start of the final pan cooking step add boiling water to keep the sauce loose. If it tastes bland add a little pasta water. If the seasoning is already right add more boiling water and continue cooking until the pasta reaches your preferred texture.

Q&A – Anchovy Lemon Butter Spaghetti
Q. Can I use less anchovy if I prefer a milder flavour
Yes. You can use two fillets instead of four. The flavour will be lighter but still savoury.
Q. Does the pasta water have to be lightly salted
Yes. Anchovies provide plenty of salt on their own. Lightly salted pasta water helps you keep control of the seasoning.
Q. Why do we add butter twice
The first addition builds the base of the sauce. The second addition off the heat gives the pasta a glossy finish and rounds out the flavour.
Q. Do I always need to add pasta water at the start of the sauce
Yes. One ladle of pasta water is essential. It helps the sauce come together through the starch and provides the base level of seasoning.
Q. Why do we use boiling water later in the cooking process
Once the initial pasta water is added you use boiling water to keep the sauce loose without adding extra salt. It prevents the dish from becoming too salty while the pasta finishes cooking.
Q. When should I use pasta water again
Use pasta water only if the dish tastes under seasoned after the first ladle. If the seasoning is already right use boiling water instead to adjust the consistency.
Q. How do I stop the pasta from becoming too salty
Taste as you go. Keep the sauce loose with boiling water and add pasta water only if it genuinely needs more seasoning.
