Shit. Really? The US box says four.
Interesting seeing the cooking instruction differences between the US & Canadian boxes.
In the US:
Classic is 4 tbsp + 1/4 cup of 2% milk
Light is 2 tbsp + 1/4 cup of fat free milk
In Canada:
Classic is 3 tbsp + 1/4 cup of milk
Sensible is 1 tbsp + 1/4 cup of skim milk
