There are 2 primary forms of mandarinquat, Nippon and Indo. It might be worth while to try and figure out what type you have. I have a Nippon, It's a fun citrus to grow because of the vigor, its a nice looking dense tree, with dark orange almost red fruit(later in the season), prolific producer & bloomer. Its alot like Meyer, not in the fruit but, the way it grows. If its not holding enough fruit it will bloom and bloom throughout the summer, until its holding so much fruit at multiple stages of ripeness(at least for me it dose). The drawback is the fruit is only moderately useful, This is surely more of a novelty tree. I have had them at all stages of ripeness and the best is very late, like now or even later, They hold well on the tree for fresh eating the begin to sweeten by this time and even beyond. The fruit gets the size of golf balls or tad bigger, they are juicy, many seeds, have sweet skin with some slight bitterness/aftertaste the flesh is as sour as a lemon if you pick them before around March(depending on your climate) I would think candied or marmalade would be very good uses.

I have had mandarinquats from Jungle Jim's international fruit market and they have a sweet rhine and sour interiour. Try juicing them to make an Indio mandarinquat pie or perhaps a mandarinquat meringue pie. And eat the solids peal and all. the solids should taste very good You'll get the best of both worlds.

Take a look at this website. It's kumquat recipes. I have a Nagami, which is a sour/sweet kumquat, and made the marmalade, and it's delicious. It's quick and easy because you have to add pectin, rather than cooking it until it makes its own. There are a lot of recipes here.

Here is a link that might be useful: look here for kumquat recipes

I didn't know there were 2 types ( I ordered Indio not knowing). Much thanks for the tree and fruiting informtion and the recipe ideas and link! So glad this won't be "only" an ornamental!

I have yet to see a nursery carry both the Nippon mandarinquat usually called an orangequat and the indeo mandarinquat, They sell one or the other. you didn't have a choice where you ordered. I have contacted many places about the culinary differences and have only got this answer, "I have never tasted the other"
