Once you have boiled it you can use it when ever you want as it as already turned into caramel there is no set time of use if you want to use it straight away let it stand in cold water till it cools get your tin opener nick an hole on the top with the can opener but be very careful it dosen't squirt in your face also if you want to use it when ready for it take out what you need put it in a container then into your microwave to heat it up hope this helps you.
Also, in the shop next to the condensed milk, you will find tins of it ready caramelised for you x.
