I like to make 1 kg batch and it keeps for all of ramadan and even months to follow, if you are making more make sure to adjust the rose water and orange blossom as well
4 cups white sugar
2 cups water
boil for 10mins (if you’d like a extra thick syrup boil for 15-20mins)
remove off heat and add 1 tsp lemon juice and orange blossom and rose water
note: orange blossom and rose water can be purchased at any arab grocer, most coles sell them as well. Alternatively you could purchase them online.
