Do Tomato Seeds Cause Bitterness in Sauces? Science or Folklore?

echoclerk Nov 1, 2012 08:16 AM

Is this just an fallacious old wives tale like "searing meat to seal in the juices" or is this grounded in scientific fact?

I've been told on various occasions that tomato seeds produce / cause a bitterness, particularly in slow / long cooked sauces. But I've never really known if its true. Does anyone have a reputable source for this idea?

ie should I be bothering to de-seed fresh tomatoes when they will be cooked for longer periods. Most French/Italian recipes (using tomatoes) do seem to recommend peeling and de-seeding.

    I suspect you might get a bit of bitterness if you really blended the living crap out of a sauce with seeds in it. I'm talking vitamix level blending though, not really something you could accomplish with an immersion blender. The seeds themselves (not the surrounding gel) might be a bit bitter if they're broken up, but even then I think it's a subtle thing.

      Apparently Cook's Illustrated / ATK just came out against the need for seeding tomatoes. In fact they found that leaving the seeds in makes whatever you cook taste much better, more tomato-y. I'll take that as permission to skip the annoying step of seeding tomatoes myself!

        IIRC what they said was that it's the gel surrounding the seeds that adds a lot of tomato flavor. But I don't seed them, either.

          Yes- it's the gel around the seeds that contains some of the most intense flavor in a tomato. If I'm making a sauce from fresh tomatoes, I often strain the gel and add that liquid back last minute off the heat to rehydrate slightly over-reduced sauce. It really ups the intensity of tomato flavor, and not cooking that liquid gives the sauce a great brightness and freshness that most sauces lack.

            great idea cowboy, I personally have
            always loved to slurp up the seeds and juice after cutting up tomatoes for a salad or whatever. Just recently I read, don't remember where, that the jell around the seed is loaded with all the good stuff. Can't wait to try your idea. Thanks

        I've been cooking with fresh tomatoes from my garden for over 30 years & have yet to de-seed one for anything. Have yet to find any bitterness.

          Lots of discussions on that subject:
