A holiday sweet treat I make for myself and that's always in demand for gifts: peppermint macaron bath bombs! I usually keep these around for when I have a cold since the scent opens up a stuffy nose, but they're great whenever you want a bit of Christmas anytime of year. I also use these in my shower--just put in the floor and allow the steam and water to mix.
- bath bomb mold (I used a macaron mold)
- 1 c baking soda
- 1/2 c cornstarch
- 1/2 c citric acid (online, canning section, health food stores)
- 2 tsp water
- red soap colorant or food coloring (I also added in some red pigment powder)
- peppermint essential oil + 4 tsp coconut oil or oil of choice
Mix all dry ingredients in one bowl. In another bowl, mix the water and coloring (and oils if doing that).
Very carefully add a few drops at a time of the colored water to the dry ingredients and mix. Be patient with this step because the mix will begin to bubble if you add too much at a time. It should look as pictured above. I made mine very, very red since normally the red will fade some once it dries--the powder pigment really helps with this.
This depends on your mold, but mine was a one piece macaron mold--sometimes they are halves that you put together. I wanted white in the middle, so I saved a little of the mix and didn't add any red coloring to it.
I put red in the bottom of the mold and really pressed it in. Then I added white (aka no color added) mix to the middle. I didn't have enough mix so I added it around the edges and it turned out well.
Then I added the red on top. For my mold, I had to make sure the top was level since this was the bottom of my macaron, so keep that in mind.
Allow to dry for an hour. Package or display. These keep for around a year, but you'll use them up before that, I bet!
