** You can use 1/2 cup cornstarch if you prefer.
Add baking soda, epsom salt and citric acid to a bowl and stir. Drizzle oil and then the essential oil over the dry mixture. Use a glove and mix with your hand. Spritz 1-2 times with the spray bottle on the top of the mixture and mix again. You want the "dough" to be just wet enough so that it sticks together. Spritz again, going 1 spritz at a time and then testing to see if the "dough" sticks.
To test: squeeze some of the dough in your hand. It should be slightly damp, slightly crumbly and definitely hold its shape, NOT wet. Although it can be a bit tricky to get the "dough" at the perfect holding state, go by the rule that it's better to have the "dough" be drier than wetter.
Now take some of this mixture and press it into one of the holes of the mini muffin tin. Use a cookie press disc and press down to compact the mixture and press a design into the bath bomb.
Line a cookie sheet with unbleached parchment paper. Overturn the muffin tin and gently tap the bottom of the tin to release the bath bomb onto the cookie sheet. Repeat with rest of ingredients. Note that if you see any hairline cracks in any bath bomb, take it up and add it back to the "dough" and add a spritz or two of water.
Let bath bombs air dry 1-2 days. Overturn them gently and gently blow or remove any bits of crumbly dough, if any. Gently place your bath bombs in a box or tin.
To use: simply pop 1 or 2 into a bath tub filled with water water. It will fizz for a bit because of the citric acid (or cream of tartar), then dissolve. Dim or turn off the lights, add some candles, and soft music, and sink into relaxation!
Bath bombs are so-called because when you add them to water, they have a fizzy reaction. This is because of the citric acid (or cream of tartar). However, you could replace this with baking soda and just make a bath puck instead --- can't call it a bomb anymore, because there won't be any fizz ;)
The oil is used to give a moisturizing effect to the bath while the essential oils give scent, hence you could use any oil you like (or none) and experiment with other essential oils.
For troubleshooting the "dough:" as mentioned in the directions of the recipe, it's better to have the mixture be drier rather than too wet. If you do add too much water, the mixture may start to react and you'll have to add in more dry ingredients to tamp down on it. Use 2 parts baking soda to 1 part citric acid. e.g. 2 Tbsp baking soda to 1 Tbsp citric acid.
Do note that different manufacturers make different sized muffin tins! I mentioned the measurements of the pan I used, however you could use ANY other solid mold (not soft like silicone), such as a mold for candles, a metal mold for chocolate, etc. Also note that if you don't have a cookie disc, no worries: just use a spoon or your fingers to press the dough into the tin. The key is to compress the "dough" together so that it sticks, and then let it air dry so that the shape is retained.
These make pretty gifts during the colder winter months, but any bath aficionado/aficionada will appreciate these little gems as well!
As always, Enjoy :)
