Cuisinart frozen yogurt recipes confusing I just bought an ice cream maker (ICE 70) and it came with an instruction/recipe book, but the recipes for the frozen yogurt are confusing. 

One example is like this


2 cups whole milk, plain Greek yoghurt 
1/4 cup granulated sugar 
4 cups frozen mango pieces 
1 teaspoon lime juice


So on the first ingredient they say two different things, whole milk and yoghurt, but am I supposed to use both, or only one of these?

For example am i supposed to use

2 cups whole milk AND 2 cups yoghurt?

OR

2 cups combined whole milk and yoghurt (1 cup each)

OR 

2 cups only of whole milk  OR 2 cups only of yoghurt (I choose which one)

Does anyone know?

The recipe says:
I read that as 2 cups of Greek yogurt made from whole milk (ie not low- or non-fat yogurt).  The comma does make it confusing, however.
