Step 1. Cover (loosely) he bottom of a pie dish or baking dish with caster sugar.
Step 2. Wash your oranges really well and dry. Use a citrus peeler, thin or thick, up to you and peel anywhere between 1 to 5 oranges.
Step 3. In a small sauce pan bring 1 cup of sugar, a half cup of water and 3 tablespoons of Cointreau (optional) to a slow boil. Stir to ensure all the sugar has dissolved.
Step 4. Add the orange peels to your boiling syrup and wait until they start to look a bit translucent. Then wait a bit more, for good meaure.
Step 5. Drain (do not rinse!) and toss in the dish with sugar (I used chopsticks for this). Let it set for 5 minutes and toss again. Repeat as many times as you like.
I plan on using it as a topping for delicious baked goods.
