Whole milk substitute

I want to make some Mexican candy (recipe below) that calls for 1/4 cup 
whole milk. We don't buy whole milk. What happens if I use 1% milk? 
Would it work but not be as rich, or would it be a disaster. If the 
latter, I'll just use 1/8 cup evaporated milk and 1/8 cup water.

Jamoncillo (Dulce de Leche) recipe

1 cup whole pecans
1/4 cup whole milk
1 cup sweetened condensed milk

Line a pie pan with wax paper.

In a blender, mix whole milk for 2 minutes. Over medium heat, boil the 
sweetened condensed milk, stirring constantly. Once it starts boiling, 
remove from the heat and add the milk from the blender. Mix well. 
Continue mixing and then pour into prepared pie pan. Garnish with whole 
pecans. Let cool before cutting into squares or desired shape.
