The original recipe asks for 375 gm clementine. I went in for more depending upon the weight.
You can replace the clementine with oranges or lemon, as desired!
I pulped the whole orange without bothering to take out the seeds. If you feel dicy, you can go through the procedure. I didn't, did give a slight tinge to the cake but I loved it.
The sugar is really mild, increase as per your sweetness.
You can drizzle the cake with more orange juice or drizzle but the cake was so moist that nothing was required.
