My milk buying guide:
Red = Milk
Blue = Diluted milk
Green = Diluted water
We go by this:
Red: good for rich treats like coffee, homemade ice cream, and chocolate pudding
Blue: no purpose, mix red+green if you must
Green: best for drinking; thinnest consistency, so gets quite cold
It was tough convincing anyone here to use the endless blue milk even in cereal. I have a young son that does NOT like water. "Milk or water" is 100% of the time answered with "milk," which usually means green around here. Then again, over the summer he drank blue, and if we have red but are low on green, he'll get straight red. I don't understand what purpose the "hating" on green serves.
Any good recipes?
Custard is complicated and not possible spur of the moment. For simple vanilla ice cream: whisk a cup of whole milk with 2/3 cup sugar (adjust to your taste), with a pinch of salt if you'd like. Add 2 cups heavy cream and 2-3 teaspoons vanilla. Whisk, chill for an hour in fridge, then pour into ice cream maker for 15-20 minutes. Best flavor addition: add a few (3?) tablespoons of seriously strong coffee (not instant, unless you actually like that flavor), use 3/4 cup sugar instead of 2/3. Try making a milkshake out of that. Best coffee drink ever.
