Step 1 - Boil water (salt it, should taste like ocean water)
Step 2- Add pasta. Cook it. (approx. 8 minutes) Try one and see if it's cooked.
Step 3- Strain pasta, retain about a quarter cup of the pasta water.
Step 4- In a separate non-stick pan, heat the butter, then add the pasta (without the water) to the pan.
Step 5- As the pasta cooks in the pan slowly stir in some of the pasta water (tablespoons at a time) enough that it dissolves as it cooks.
Step 6- Add the lemon juice and saffron water, stirring into the pasta. It should turn a golden yellow.
Step 7 - Top with all the Parmesan cheese you want and then serve!
