Citrus.

I haven't had clementine before I came here. 
​According to wikipedia, it is crossing mandarine orange and sweet orange.

First time I knew about the orange was in a movie, Secret life of Walter Mitty.The main character's mom made a clementine cake for him. 
I was inspired by it and made a cake when I saw it.
​Anyways, it was a few years before and was with regular oranges.
This time, about a month ago, I saw a box of clementine and seemed like it was from middle east..I was curious how is the taste of the oranges then bought it.
The clementines were taste so good.Sort of special for me, the balance of sweetness and tanginess were perfect.However..I didn't think I will finish just eating one small box of fresh oranges before they went bad.
I dicided to make marmalade. 

The ingredients are simply, just clementines and the same amount of brown sugar (or white sugar if you like lighter color).
You can use less sugar, but don't decrease too much.
The method is a little bit of work with clementine because they are small and have lots of seeds.
I am writing recipes here as simple and easy..so this is a little bit lazy way than traditional marmalade recipe.
Wash the clementines, take the orange skins off from the fruits. Don't leave too much white skins.
Normally take out of fruits meats from the segments but so, this is "easy" way, juice them with cheese cloth.
Then keep the white skins and pulps, put the juice and sugar into the pot.
Wrap the skins and pulps with cheese cloth and close it. This components are for pectin. 
Chop the orange skins. Very thin julian, or the size of your choice.
Put the chopped skins, the cheese cloth bag in the pot of Juice and sugar, and stew them.
First medium heat, once it went boiling, reduce the heat, simmer it with very low heat for 40min -1 hour or more until the orange skin got softer.
