The biggest problem with creating these shamrock bath bombs was trying to figure out what scent to make them. I was thinking of St. Patrick’s Day, of course. Sadly, no Guinness or Lucky Charms scented oils were to be found. I ended up taking the easy way out and using lavender. According to Google, there’s a minor amount of lavender production done in Ireland, so we’ll go with that as the reason. It’s definitely not the fact that I had it on hand already and had no better ideas…
Besides, I nailed it on the color and shape. That counts for something, right?
The more I make this recipe, the more I realize that it’s pretty fool-proof. I had some rough goes with it as I fine-tuned everything, including some overly-puffy, too soft nightmares. This final version of the recipe is hard to mess up!
Start by combing the dry ingredients in a large bowl and the wet ingredients in something that is easy to pour from. I typically use a small measuring cup with a spout. Slowly add the wet mixture to the dry mixture, stirring the whole time. You’ll create a kitchen volcano if you pour too fast. You want to avoid the bubbling reaction as much as possible, as that’s taking away from the in-bath bubbling. As soon as the ingredients start to hold their shape, stop adding the liquid. It should now feel similar to kinetic sand.
Pack the mixture tightly into the mold and allow it to dry overnight. The recipe as-is should make three full shamrocks in the mold featured. Increase accordingly if you want to make more!
After they’re dry, pop your shamrocks out of the mold and they’re ready for bath time. Remember to store them in a dry place!
