There are some corn/rice pastas that are pretty close to the real deal. Sure a seasoned pasta officianado could tell the difference, but we have gluten intolerant in the house so predominantly eat gluten free pastas. Never had a visitor or kids friends complaining (and kids will complain about anything). Happily chow down. There are also some pretty good grain free varieties made from tapioca and egg, we get lasagne sheets that are approved of by the only real Italian I known, they maintain the chewy/rubbery texture of lasagne well.
Yeah, the Rummo Gluten Free pasta is just on another level in the UK vs the own-brand stuff. Thank goodness!
