Following are the steps shown to make sugar syrup in the right way.

Take sugar and water in the ratio of 2 : 1 1/2 unless other wise mentioned.

Put both in a deep saucepan to boil, stirring occasionally.

When the mixture comes to a boil, add 1/2 cup milk.

When a thick scum is formed on the surface of syrup, it is time to strain.

Always use a metal strainer or moist cloth to strain the hot syrup, never plastic.

Put back to boil, checking the consistency required as above.

Check frequently, because once the first thread forms, it proceeds tothicken to the next stages very quickly.
