International Delight is my choice of coffee creamer (regular, not the fat-free or reduced sugar versions), mainly out of laziness. A single shot adds both sweetness and creaminess together. I am always looking to simplify my life.
This is not a product endorcement, just what I happen to use. You may prefer other brands. They are all about the same to my plebeian taste. I have even started to use a much cheaper store brand.
I have noted in the past how much it tastes like melted ice cream. My wife uses it to make a quickie root-beer float and I admit to sampling a little straight out of the bottle for an occasional treat (which is one reason why we have so few guests for dinner). I suspect many others have discovered this off-label use, too.
The reverse also works. If you run out of creamer/sweetener you can just add a teaspoon of ice cream to your coffee instead.
That’s all. Just an observation, no profound insight.
