Do you cook your pasta in a large pot, with plenty of boiling water, and a good amount of salt? Usually I just stir once just after putting the pasta in, and I never have noodles sticking together.
My pot would have to be 3x its size to fit the amount of water a single package of pasta says I should use.
1kg to 10l
Do you have a bathtub in your stove?
1 kg of dry pasta is enough for 10 people! Do you often cook for that many people? (Genuine question)
This is making me chuckle, because I just did this last night for a dinner party. It was a hell of a lot of pasta for 7. I kept it moving, even in my big stock pot. Only a few strands stuck to the bottom. We have leftovers.
I usually cook a quarter of that for the two of us, sometimes half if I want to eat for a couple of days.
2lbs/1 kg is a lot.
I have a 12 gallon pot I use for the same.
If it didn’t have the spout off the front I’d probably use it for a lot more stuff like huge batches of chili (for canning). I end up using multiple pots for that instead because I don’t want to have to clean around the dumb thing.
But the drain tube makes it soooo easy to strain the broth.
