Boil the pasta in water until tender, save 1 cup of pasta water for use later.
Add some oil, salt, and fresh herbs in the water when cooking the pasta. Drain and set aside when done.
While pasta is boiling, wash shrimp.
Melt the butter over medium heat, then add the shrimp.
Let it cook till a little pink and starting to curl. Then add garlic.
Cook for 5-7 minutes and then add oil. Continue to stir until shrimp is pink and curled.
Add pasta to skillet. Add seasonings, pepper and pepper flakes. Add just enough of the saved pasta water until it is not dry but not swimming in liquid either. Depending on amount of pasta this requires 1/2 the cup or all of it. Start with adding 1/4 of it and add as needed.
Keep tossing all ingredients around in skillet until all is incorporated and hot. Enjoy!
