Seeding a tomato actually means removing the seeds with the pulp, leaving the skin and the fleshy part attached to the skin. In other words, you don’t have to pick through the pulp to remove the seeds. The pulp goes out with the seeds.
Seeding tomatoes is easy to do once you do it. No matter what type tomato you’re seeding, cut both ends off. Then, cut the tomato in half from end to end.
Now, you can either use your fingers, a spoon or a knife to scoop out the innards going from one side to the other. And that’s it. You’re left with clean tomato shells.
