Mildred:

Just to be sure we understand your football problem point, would you try the following and let us know what you get?

Take an empty one-quart measure, add 28 ounces of water, then pour off 4 ounces into a cake batter bowl.
Next, add 10 liquid ounces of water to the one quart measure, plus 2 liquid ounces of cooking oil. Mix well.
Pour 7 ounces of the mixture out of your quart container into a separate bowl, to be used later.

Now–How much liquid do you have in your one quart measuring container?
a. none.
b. one quart.
c. 29 ounces.
d. huh?

For a thinking person, you see, it does make a difference.
Don’t forget the paper towels.
