Tomato sauce.

[Piglet]

I have an immersion blender for that. I love that thing, I highly recommend them.

After cooking the pasta add a good splash of the water in the sauce, the starch will make the sauce cling to the pasta, just a little though.  Never heard of an immersion blender.  The important thing is to cook down the toms, the water needs to evaporate.    Italian babushkas  would spend a day making this sauce, it can be done in 30 40 minutes.
