In order to make this soup, it is recommended to use some specific equipment. First of all I use the Instant Pot to cook it. If you want, you could also make this soup on the stove, by bringing the ingredients to a boil and then letting them simmer for an hour.

Once the soup is cooked, it is pushed through a food mill. Food mills are perfect for getting the seeds out of a liquid of cooked tomatoes. It also takes the skins out easily. Then the soup is pushed through a mesh sieve to get the smallest seeds out and a bit more of the roughage, making it nice and smooth.

I also like to use an immersion blender to mix in the olive oil, but a good long spoon should do the trick just as nicely.
