Step 1Bring three 3-quart pots of water to a boil. Use a small knife to score the oranges into quarters (cut through the peel and pith but not through the fruit). Remove the peel; set aside the fruit for another use.
Step 2Add the peel to the first pot of water and simmer 2 minutes and then drain. Repeat two more times in a new pot of boiling water.
Step 3Drain the blanched peel on paper towels and pat dry. When cool enough to handle, cut the ends off each piece of peel so that you have straight edges, then cut it crosswise into quarter-inch strips.
Step 4In a large pot, combine 4 cups sugar and 4 cups water. Bring to a boil and simmer 5 minutes, until clear. Add the cut-up peel to the simple syrup and simmer gently 2 hours until the fruit looks translucent. As the peel is simmering, skim off any foam from the syrup.
Step 5Lightly oil a cooling rack and place waxed paper underneath. Use a slotted spoon to remove the peel from the syrup and place the strips in a single layer on the rack. Let the candied fruit peel dry overnight.
For the candied Meyer lemon peel: Remove and blanch the peel of three Meyer lemons as in the candied orange peel recipe. Cut the peel into strips and simmer in the simple syrup 1 1/2 hours until translucent and glazed, and proceed as in the candied orange peel recipe. Makes about three-fourths cup.
For the pink grapefruit: Score two pink grapefruits into sixths and remove the peel and pith from the fruit. Blanch and cut into strips as in the candied orange peel recipe. Simmer the cut grapefruit peel 2 hours in the simple syrup until translucent and glazed, and proceed as in the candied orange recipe. Makes about 3 cups.
For the pomelo: Score one pomelo into eighths and remove the peel and pith from the fruit. Blanch and cut as in the orange peel recipe. Simmer the strips of pomelo peel 1 hour in the simple syrup until translucent and glazed, and proceed as in the candied orange peel recipe. Makes about 3 1/4 cups.
For the cranberries: Do not blanch the cranberries. Simmer half of a 12-ounce bag of cranberries in the simple syrup for 1 1/2 hours until they are translucent and glazed, and proceed as in the candied orange peel recipe. Makes about 1 1/4 cups.
