Heat a large enough sauce pan on a stove on medium. Add the milk and Sodium Citrate. Bring it to a boil while whisking. The moment it hits boiling point: turn off the heat.
250 gram Milk, 5 gram Sodium Citrate
Stir in all the cheese and keep whisking until all the cheese is melted and you have a creamy texture. This perfect cheese sauce is that easy. Note: If necessary, you can heat it up a little if the cheese hasn't melted yet or the sauce becomes too thick. You can store this for a couple of days in the fridge.
