I previously made a 3 lb batch of this and cured it for 3 months – it was a big hit, so I decided to use a 5 lb mold and make a couple changes:
What is Bastille soap?
Bastille is soap made with 70% (or more) olive oil and contains other oils or butters. Olive oil is extremely gentle, making it the perfect oil for delicate or sensitive skin. This recipe also uses luxurious and emollient buttermilk. Buttermilk is an excellent skin softer. It has lots of moisturizing properties, along with alpha hydroxy acids that are great for dry, sensitive, and delicate skin.
Carrot puree: Carrot is known for its antioxidant properties. It is also used for help in anti-aging, preventing wrinkles, speeding scar reduction, and can add elasticity & tone to skin.
Red Palm oil also bumps up the color and is regarded as one of the most nutritious oils in the world. Palm fruit oil contains mainly palmitic and oleic acids and is about 50% saturated. The health benefits are attributed to the high content of carotenes, which include beta-carotene and lycopene. (These powerhouse antioxidant nutrients are more that tomatoes or carrots have.) It’s also densely packed with numerous tocotrienols – a powerful form of vitamin E.
Colloidal Oatmeal is wonderful for extra dry skin, is non-abrasive, and it also alleviates itchiness.
All these skin-loving and gentle ingredients make this bar great for babies, young children, adults with sensitive skin, and those who want to really pamper their skin.

86 oz Batter/Colors:
86 oz natural soap poured over mat on bottom of mold.
Rest of batter used for samples and FO testing.
I trimmed a fondant mat to fit the bottom of the mold (which will become the top). Since the 5 lb mold is so long, I had to add another piece of mat to completely cover the bottom.
I soaped the lye and liquids at 105F & 103F, and poured the lye liquid through a strainer (no undissolved milk or any bits caught); stick blending about 4 times more than usual to reach a very light trace (using an immersion blender). I had thought of using my super powerful stick blender, but am glad I didn’t, as both milk and red palm oil accelerate trace. (In this instance, it meant instead of stick blending for what seems forever, it was less blending.)
I poured the batter into the mold at a very light trace, over a new impression mat cut to fit the mold. I waited for it to set for 15 minutes, then put it in a dedicated soaping refrigerator to prevent the milk from overheating.
I soaped quite a bit warmer than usual, but I knew it would take a while for the soap to set up, due to all the Olive oil in it (and the higher temperature would help it set up faster).
I was really surprised at how yellow this soap is – I expected an orange color from the Red Palm oil. I was also astonished when I cut it and found a big oval circle inside (see last photo). Despite putting this in the refrigerator for 24 hours, the middle of the soap had gelled. The circle dissipated some as it cured, but it is still very visible in all but the two soaps at each end of the loaf. Since the soap is so yellow, it makes me think of a big egg inside!
The gelling was probably helped by soaping at a higher temperature. Soaping lower and/or putting it in the freezer for a while would prevent this.
The little dots on the soap are caused from the wire cutter. Next time I will wait a bit longer before cutting.
