The lesson in this is...

....when a recipe calls for "bottled horseradish"....don't get distracted at the store and then accidentally buy "horseradish sauce"...it may look very similar on the shelf, so similar you don't realize what tragic misstep you've taken until you get home and are measuring it out...it's loaded with high fructose corn syrup and will change your recipe's outcome for the dismally inferior.
