The Best Candied Citrus
recipe based on the method from Brownie Bites Blog
4 oranges, preferably organic (or the equivalent amount of other citrus)
1 kg (2.2 lbs) sugar, plus additional sugar for each day. (you will need a total of 2.4 kg or 5.3 lbs of sugar)
600 g (21.5 oz or approximately 2.75 cups) water
Slice the oranges into thin rounds, no more than 1/4 inch thick. Fill a bowl with ice water and set aside.
Bring a pot of salted water to a boil. Add the sliced oranges to the boiling water (may need to be done in batches depending on the size of your pot). Scoop from the boiling water when the slices float to the top and place into ice water to cool. (They should cook no more than one minute) When cool, drain and remove the slices from the ice water and transfer to a container large enough to hold all of the slices.
Place the sugar and water in a saucepan and bring to a boil, stirring to dissolve the sugar. This step is to just dissolve the sugar (not to cook the syrup). Pour the hot syrup over the orange slices. If the orange slices float, weigh them down to keep them fully submerged. (The easiest way is to place a plate on top of the orange slices and a glass jar of water on top of the plate)
Store the submerged orange slices in a dark cool place, like a cupboard or closet for the duration of the candying. They do not need to be refrigerated.
Each day increase the sugar content of the orange slice sugar solution. Do this by draining off the sugar solution the slices are submerged in, add 100g of sugar, heat the solution to just dissolve the sugar, and pour back over the orange slices. Complete this increase-sugar step daily for two weeks.
Once finished with this process the candied oranges will keep in the solution for a very long time. When ready to use them they can be finished in the following ways.
Remove the orange slices from the sugar solution. Arrange in a single layer on a drying rack out at room temperature and let stand until less tacky, 1-2 days (longer if it is very humid). Turn them after one day to make sure they dry evenly. Once dry they can be finished by rolling them in sugar or dipping them in tempered chocolate.
Store finished candies in an air tight container to keep out humidity. They should last at least a month if kept well sealed (and away from nibblers like we have in my house.)
