This recipe is from mum
You will need :
1.Lemon or lime( I saw some ‘local/ kampong ’ lemon at the pasar malam and used these) 
2.Coarse salt 粗盐 (how much you need will depend on the quantity of fruits that you have)
3.Glass jar for storage ( the big Horlicks or Nescafe jars are suitable or any glass jars will do)
a)Boil water and while waiting for the water to boil, wash the fruits 
b)Drop the fruits into the boiling water and leave to boil for 10 – 15 minutes
c) Remove fruits from heat and leave to cool on a sieve
d)Pack the fruits with salt into the jars
e)Leave the lime/lemon in salt until the fruits are wrinkled – this takes about ~ 2 weeks for the lemon I tried. (After 1 week , I found that I could pack all the fruits into 1 jar ( I started with 2 jars)
f)Wash the salt from the fruits. Place the fruits on a plate and steam them for about 5 – 10 minutes . the fruits will bloat during the steaming and will very quickly wrinkle when heat is removed.
g)Leave the fruits to cool and pack them into dry jars for storage – and the pickles are ready.
For making delicious and refreshing drinks, use a folk to breakup the pickled fruits ( and squeeze some fresh lime juice for the extra umpphh) , add sugar syrup , add some ice cubes. This is also a good remedy for clearing phlegm-omit the ice cubes.
h)To make the sweetened version of pickled lemon/lime- after steaming the fruits, make some thick sugar syrup and pour them into the storage jar, leave for 2 weeks or so.
NB: the salt can be recycled, run some water over the salt to rinse it ( make sure you don’t use too much water and dissolve all the salt lah ), let them dry in a sieve and store them into a container until your next project.
