So, what's in this prepared horseradish magic? Well, aside from the obvious horseradish root, you've got salt, water, and vinegar – the holy trinity of condiments. Some brands might throw in some spices and flavorings to give it an extra kick, but don't worry, it's all still horseradish-tastic!
Now, you might be wondering, why vinegar? Well, my curious friend, it's because vinegar helps to mellow out the heat of the horseradish (just a bit, don't get too excited!). It's like the horseradish whisperer, soothing the savage beast that is the horseradish root. Okay, maybe that's a bit of an exaggeration, but you get the idea!
