Orange, Grapefruit, Lemon
Knife
Any type of oil, Vegetable, Olive, Canola, etc.
Methode:
Firs You Should eat the middle portion of the orange (Vitamine C)
and being careful to leave the middle stem like portion intact.
I found removal easiest by using a sharp knife and digging out the middle starting with the edge closest to the outside of the orange.
*Caution - Do not ingest the orange if you have extreme citrus allergies
