If you didn't/couldn't grow your own ingredients, or you didn't/couldn't make it to a farmer's market, you can buy all the ingredients needed at your local grocery store. I actually bought fresh horseradish along with the tincture bottles with dropper tops on Amazon.
These are 2 oz. size. The recipe yielded 1 dozen 2 oz. bottles and 1 pint - for refills.
This particular batch is hot, but it isn't crazy hot. The recipe calls for including the pepper seeds when combining everything. I, unfortunately, had discarded them, and then realized I was supposed to include them. I was kind of afraid to work with the hot peppers - I wore rubber gloves and discarded the seeds because they are usually the hottest part of the pepper...which is why you need to include them. Light bulb moment for me.
This is super easy to make. If you are interested in a natural way to help you through a congestion or sore throat bug, I encourage you to give this a try. Because this is infused vinegar, it doesn't expire.
