Pasta Cooking Tips:
- • Use plenty of water - at least 4 quarts per pound of pasta
- • Salt water generously - it should taste like the sea
- • Save 1 cup pasta water before draining for sauce
- • Cook to al dente - pasta will continue cooking in sauce
- • Never rinse pasta unless making cold salad
- • Toss immediately with sauce to prevent sticking
