It's over bros/siss/xes
I boiled the pasta, and instead of draining the water, I accidentally added the tomato sauce into the water with the pasta. My pasta is now soup.
The only saving grace is that I usually undercook my pasta and eat it crunchy. So I can still reduce the "soup" a bit before it becomes overcooked.
I just tasted the pasta. I added salt to it which was a mistake because the sauce I bought also has salt in it. I now am beginning to understand how that "if I cook even the simplest of food I will somehow fuck it up and poison everybody" gag in anime works.
Next time this happens, you can strain the soup and cook the liquid down, then re-add the pasta.
