2 tblsp butter (or I use Nuttelex).
2 tlbsp plain flour.
600ml milk.
1 cup grated cheese.
Melt butter.
Add flour and stir for 3 minutes (this cooks the flour, ensuring there are no lumps).
Remove from heat.
Slowly add the milk, little by little, stirring all the time.
Once all milk is added, replace on gentle heat and add cheese.
Stir until thickened and smooth.
