Spoon sweets - Bitter Orange

Version A 
Grate the bitter oranges on a grater to remove the peel. Cut each one in 4. Place them in the pot with enough water to cover them and bring to a boil. Remove from the heat and replace the boiling water with cold water. Roll them up one by one and secure with toothpicks. Place them in the pot with enough water to cover them. For four days change the water once a day to remove the bitterness. On the fifth day wash them well. Place them back in the pot and add the sugar and 5-6 glasses of water and place on low heat to cook slowly. When the syrup is ready, remove the toothpicks, put them in glass jars and cap them. (Pepa Frixou, Pachna Limassol)

Version B 
Wash the bitter oranges and grate them on a fine grater. Cut them into 3 or 4 equal parts and remove the inner skin. Roll each peel and secure with a string. Cover them with water and bring to a boil. Remove and place aside. For the next 4 days, change the water every day (use cold water) and let them cook very well. Success depends on proper cooking. On the last of the 4 days, drain them, sprinkle them with cold water and remove the thread. in a pot, place the bitter oranges and add the sugar, water and lemon. Leave them overnight to allow the sugar to dissolve. On the following day, bring them to a boil for a while. Remove from heat and set aside. On the following day, boil them until the syrup is ready. Skim them and add the vanilla. Once cool, transfer them to glass containers. (Charalambous 2006, 302)
