I have meiwa kumquat.I love it.Leave the fruit on till its ripe.It will turn orange.they'll feel firm.they are ready when you can feel a lil give in the skin when squeeze(less hard) They taste better if roll them in palm 1st it releases the juices.They are good in tequilia,you can make pies,add to salads.add to hot tea good in green tea.I have a jar of this currant seasons fruits infuseing with brandy(spagetti jar full of kumquats with X in each end 1 cup sugar and top off with brandy or choice of liqour.kept shaken daily 1st 2 weeks then once or twice a month a good& I'll keep topped off for at least 3 years but 5 is perfect....if can wait Keept in cool dark corner...my cabinet

)
oh!I forgot.I grilled some with chicken on a kabob once and we're yummy grilled& I chopped up 8 kumquats one nite and added honey& soy sauce over pork chops.we're yummy too though was for manderian oranges.Meiwa's are sweeter than nagumi's meiwas are round naguni's are oval?egg shaped....more of what's sold in grocery stores.
