Also how much salt you have added, the size of the pot and water volume (maintaining a boil), whether the lid is on/off/partly covering the pot, energy output of the heat source...?
And to be perfectly honest i like my pasta slightly past 'al dente', especially when cooking dry pasta.
In the past I really struggled cooking pasta in the times shown on the packets on my home sovetop, but then learned to properly use the lid of my pots.
I fully cover the pot with the lid to bring to the boil, add the pasta and leave the lid partially over the pot (~70% covered) to maintain a 'rolling boil', and now it cooks more consistently and quicker.
You don't need to listen to ads. Spotube or XManager for Android based devices, or just listen in a Firefox based browser with reasonable ad blocking from your PC or laptop. I don't have premium, but I never hear ads.
The cook time varies a lot based on how dry the pasta is, which depends on how old they are, how they've been stored, and the air humidity where they're stored. It can vary as much as ±5min. Even on a conventional stovetop, it takes about 30s at most to come back to a boil after you drop in the pasta.
The best way to get perfectly cooked pasta is to regularly check on them.
In any case, I'm cross-posting content from .ml comms to the nearest non-.ml comm as part of ongoing boycotting efforts to reduce .ml's influence to make defederation an easier decision for admins everywhere because of the .ml admins insistence to push their Tankie ideology through various means from censorship of views critical of Authoritarian regimes such as Russia or China to allowing propaganda outlets (such as RT) to flourish
So to that end, if you'd like a less clogged up feed, you can always Instance block .ml
For what it’s worth, I’ve been boycotting ML since I started my LBZ account (8 months ago now), and I’ve found there is more than enough content without relying on ML.
(And as you can tell by my post and comment count, I am addicted to lemmy, like I’ve made a decent amount over 4k contributions).
