This may depend on the recipe.
Simmering with a lid on uses less heat than with the lid off.
Leaving the lid on means that evaporation will be lower - but sometimes the purpose of simmering is to reduce the amount of fluid.... so this may be necessary.
I always do it lid on and on low heat.

It is better to simmer with the lid off. The purpose of simmering the sauce is to reduce it, or to boil some of the water out of it so that the flavors in the remaining sauce are more concentrated. If you leave the lid on, then droplets of water will form on the underside of the lid and will fall back into your sauce, defeating the purpose of simmering for a long time.

well it depends if u mean gone off or simply made badly?
I use a glass jar with a screw on lid. It can be frozen and put into the microwave with the lid off to thaw. So, there are several advantages using the jar.
Basically all you did was rinse your spaghetti after you cooked it. You removed the starch which makes the sauce stick. When you do this the pasta becomes waxy and the sauce will run off. Contrary to popular reading, I quit rinsing my pasta after cooking, with the exception of elbow noodles. If you overcook your pasta, you're not allowing it to absorb that last bit of moisture out of the sauce. Best way to avoid watery sauce is to take your pasta out of the boiling water when it is not completely cooked (this is called "al dente"), then, without rinsing it, finish your pasta in the hot sauce until you reach the apropriate doneness.
strain off excess water from pasta, than saute pasta and sauce together.
No. The citric acid in the tomatoes changed the copper oxide back to copper.
at least 6 hours. this time for this sauce to completely cool. if you cool it to soon it will cause the tomatoes to give off a very strong acetic taste.
Hell with the Lid Off was created in 1990.
There's a latch on the side of the lid, lift up to pull it off.
Yes, the solvent of the polish will evaporate when the lid is off the bottle.
It means take the lid off the top of the cookpot.
