don't worry, pomelo isn't bitter! at least the ones i have had haven't been. on the contrary, its quite sweet and has a slight sourness to it. it has the texture of a firm grapefruit but the taste of a lemon and orange mixed together, that's the best way i can describe it :-)Never tried it.. never even heard of it! I'm not sure! I might find it yuck though if it's bitter
Pistachios?
