I canned tomatoes this summer and want to use them to make a sauce. Do I have to remove the seeds from them? I don't have a food mill so I am not sure if I can just use them as is.
Many recipes tell you to scoop out the seeds, but recently I have been reading that the seeds and the gel they sit in are very flavorful. Now I don't bother with that step.
For a basic tomato sauce, you don't have to remove the seeds and I personally wouldn't in the interest of keeping things simple. But it's just a preference. There are some recipes calling for tomato sauce or puree that are better seedless, depending on desired texture and appearance.
I would advise not to remove the seeds. It may make the sauce slightly more watery, meaning you have to cook it down a little more, but there is flavor (and texture) in those seeds. Not to mention the blood, sweat, and tears that went into growing those tomatoes! Every time I reflect on my own tomato patch and the struggle of getting to harvest, I shudder at the thought of throwing any of it away.
