# Expert Tips:

01 -
  • Everything happens in a single pot, which means less cleanup and more time actually tasting what you made.
  • The spice builds naturally as it simmers, so you get layered heat instead of a one-note burn.
  • It's ready in thirty minutes flat, yet tastes like you've been nursing it all afternoon.
02 -
  • Stir frequently while it's simmering so the pasta doesn't stick to the bottom and burn—this isn't a set-it-and-forget-it situation.
  • The residual heat after you remove the pot will continue cooking the pasta slightly, so pull it off the heat when it's just barely al dente, not soft.
03 -
  • If your pasta is cooking faster than the liquid is reducing, you can cover the pot for the last few minutes to trap steam and slow the evaporation.
  • Save a splash of pasta water before draining, even though there's barely any liquid left—sometimes a tiny bit of that starchy water helps bind the sauce together even more smoothly.
