To make the candied peel, remove the peel of 1 orange, cut it into strips and add to 3 cups of water. Boil the orange peel for 6-7 minutes. Discard the water and rinse the peel. Repeat the process one more time.
In a pan add 2 cups water and 1/4 cup sugar mix and let it boil till the sugar gets dissolved completely. Add the boiled peels to this mixture and cook for 25-30 minutes on medium flame till there is almost no more water left in the pan and peels get nicely coated in thick sugar syrup.
Put a cooling rack over a plate and spread the candied peels on the rack so that all the excess sugar syrup gets dripped off the peels. Allow the peels to reach room temperature.
Cut the candied peels into small pieces and keep aside.
In a bowl sieve all purpose flour, baking powder, baking soda, orange zest, and salt.
In another bowl mix the sugar, oil and orange juice.
Now add the dry ingredients to the wet ingredients and mix. Next add in the chopped, candied orange peel and gently fold it into the cake batter.
Grease a pan and add this mixture to it. Bake in a pre-heated oven for around 35 minutes at 180 degrees Celsius or till it passes the toothpick test.
Once done, take it out of the oven. Allow it to rest on a cooling rack for a few minutes and then cut into desired pieces. Enjoy with a cup of hot tea/ coffee.
