Transfer mixture to a saucepan and bring to a simmer over low-medium heat (about 5 mins).
Once simmering, the mixture will thicken. Reduce heat to low and continue to stir for an extra 1-2 minutes then remove from heat.
Cheese can be eaten immediately or saved for later. If saving for later, shape into a ball then freeze or chill in the fridge.
Notes
Cheese will keep in the fridge for 1-2 weeks or 2-3 months if frozen.I recommend freezing - makes the cheese easy to grate and has very little effect on the texture when reheated.
