*No need to bust out your small-batch, ultra-aged, super-special bourbon for this recipe. Just make sure you don't use anything from the bottom shelf.
** You want to be certain that you strain out all of the solid materials from the bourbon. Any leftover particles will breakdown over time and have an adverse affect on the taste. You should strain out the bourbon with a fine-mesh basket strainer or a coffee filter. Store in the refrigerator for up to 2 to 3 months.
