Lemongrass Rebatch Soap
This recipe is for making 5 lbs of lemongrass soap, but feel free to adjust the levels of ingredients depending on how much soap you’d like to make.
What you’ll need:
- A 5 lb box of your favorite Rebatch Soap Base
- 50 ml Lemongrass Essential Oil
- ¼ - ½ tsp Annatto Extract Powder diluted in 1 tsp warm water
- ½ cup Calendula Petals
- 2 Heavy Plastic Freezer Bags
- Double Boiler and a whisk
1. Fill a large stock pot half ¾ of the way with water and bring to a boil. Place desired amount of grated soap in a heavy weight large zip lock bag, seal and then place inside a second zip lock bag, ensuring both bags are sealed.
2. Place bag of grated soap in pot of boiling water and cover with lid. Turn heat down to medium – low and gently boil for 1 hour.
Alternatively, boil water in the bottom chamber of a double boiler, reduce heat to medium-low and place the rebatch soap in the top chamber. Ensure that it is covered with a lid and boil for 1 hour, whisking once.
3. During this time, prepare your molds and any other additives you may be using.
4. After the hour, using oven mitts, carefully remove the bag from the hot water, place on a towel on your counter and gently mush/knead the bag until soap is a smooth, even consistency. If you can still see some soap gratings, place bag back in hot water and boil for another 20-30 minutes. Carefully remove from water and repeat kneading. Note: If you still can’t get all the soap to a smooth consistency, add from 2 – 4 tbsp. of water per pound of soap base and put back in the hot water for another 20-30 min.
If you are using the double boiler method, stir with a whisk and if a smooth consistency cannot be reached, add from 2-4 tbsp. of water per pound, whisk in, cover, and boil for another 20-30 minutes.
5. Once your soap has reached the smooth consistency, add any essential oil, fragrance oil, color or other additives and knead or whisk well to distribute. The texture of the soap should be similar to thin mashed potatoes.
6. Snip off the corner of your bag and then pipe into your molds or spoon in, making sure you fill all sides of your mold. Cover your mold with a piece of freezer paper and let sit until hard. Remove from molds. Depending on how much water and other liquid was added to the soap, it may need to cure for up to a few weeks to create a hard bar with great longevity.
Note: The rebatch method produces soaps that are not perfectly smooth and consistent; the finished product will be more rustic-looking and have more character than cold-process soap.
