Shalom S-T-B,
I don't season hot, cooked pasta, but I do add seasoning to the water during cooking to infuse a flavor or two. I also use this technique for potatoes, grains, and rice.
My epiphany came when thinking of why I would cook something in plain, flavorless water when I can impart flavor in the cooking liquid. So I embraced the method...
Note 1- If I don't want the solids, I use a wire mesh tea ball for peppercorns, bay leaf, rosemary, etc. in the cooking water.
Note 2- For pasta and potatoes the increased expense of needing to add enough seasoning to also season the water I dump down the drain...
For some pasta dishes onion and garlic powder as well as dried basil and bay leaves in a tea ball.
I typically use dry mustard for the potatoes for potato salad.
Essentially using mint tea for some Moroccan couscous or bulgar dishes.
Have fun!
