If you cooked it and it’s gummy, you probably overcrowded the pot. Pasta needs room to breathe—like teens at a concert. Next time, use a bigger pot.
If it’s still crunchy, your water wasn’t boiling hard enough. Water shy of a boil is sad water. Make it furious next time.
And if you forgot to salt the water? Just whisper “sorry” to your taste buds and add more salt to the sauce. Everyone makes mistakes. Even I once dumped frozen pasta into cold water and waited. It didn’t go well.
