Because the juice from the tomato gets released from chunks of tomato in the sauce. Also when the tomato gets blended to make the sauce, the juice is left in the sauce.
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.
Well there are a couple possible reasons. Firstly, you may not have drained the pasta completely, so the water may still be trapped with it and is mixing with the pasta sauce. If this is the case, tossing the pasta when it is in the colander or getting a colander with more/finer holes might help. Or maybe what you're observing is just the pasta sauce changing in consistency because it is warm.
2 cups of cooked pasta is usually between 200 to 400 calories, depending on what kind of pasta(whole grain pasta 200) and a cup of spaghetti tomato sauce is around 330 calories which also varies.
yes. It is one sauce which can be served over pasta.
the pasta sauce should be cooked first
The basic ingredients are the same. In fact, any tomato sauce recipe can be used as a spaghetti or pasta sauce or as a pizza sauce. However, pizza sauce should have a thicker consistency than most spaghetti sauces. Watery sauces will soak the crust and leave you with a soggy pizza. If leftover or store bought spaghetti sauce is going to be used on pizza, as is with no 'doctoring', reduce the sauce by simmering in a sauce pan until it has the consistency of a thick pancake batter.
spaghetti
Yes, spaghetti is a pasta (noodle) made from wheat, egg, and/or water. It is cooked before eating and usually has a sauce, butter or other oil added for flavor. Yes, you can eat spaghetti...as long as my sister-in-law doesn't make it!
Pasta is cooked and served with a (usually) tomato based sauce with added herbs.
Pasta is pasta, whether it is cooked or not. They should be the same. The only difference would be if you added something (butter, oil, sauce, ect.) to the cooked pasta.
You haven't said if that is just pasta, or including sauce. I would say 2 people if pasta and sauce.
This spaghetti sauce is made with ground beef, Italian sausages, onion, garlic, prepared marinara sauce, tomatoes, and herbs. Serve this meat sauce with hot cooked spaghetti and Parmesan cheese.
