For every orange:
g. 50 sugar
g. 50 glucose
How to make the Candied orange peels:
Wash and dry the oranges (the thick peel ones).
Cut the peel into strips 5cm long and 3mm.
Put them in a saucepan, cover with water and simmer for an hour.
Add sugar and glucose. Stir until they are dissolved. Bring to a boil.
Allow cooling uncovered. The next day you simmer for a couple of minutes, cool again.
Repeat on the third day. If you add a little ‘more sugar and glucose is obtained from an excellent sauce to use over ice cream.
To make preserved lemons use the same procedure but discard the water that is used to boil them (until the peels become non-transparent) because it is bitter.
Besides, it usually takes five days for full effect candy.
The lemons should be thick rind.
I usually do not cut the peel into strips, but I leave them whole, preserved in the refrigerator, and then cut at the time of use.
