If you are interested in learning how to make castile soap, I can definitely say it’s one of my favorite homemade soap recipes.
This castile soap recipe is a very mild pure soap and one of the best to make if you’re new to soapmaking.
Although when you make castile soap it should really be made with 100% olive oil, I personally find it a little soft and slimy, plus it can also take hours to reach the right consistency.
So like most modern day soap recipes I’ve added a couple of other base oils to balance things out. This creates a soap that will still hold the mildness of a good old olive oil soap recipe, but in my opinion has a better feel and texture to it.

Photos From Making This Castile Soap Recipe:
Castile soap is actually a lovely pure soap by itself but because it is such a light colored soap it looks particularly attractive when topped using a colorful flower or herb.
If you are topping a freshly made batch of soap, cut the soap into bars and then firmly but gently push the top of each bar into a shallow tray of flowers or herbs, shake off any loose flowers then cure the soap as usual.
If the soap has been created and cured for some time you will have to dampen the top of soap with water and give it a bit of a rub making it nice and sticky before dipping it into the flowers or herbs.
You can find these dried flowers in the bulk herbs and spices section on Mountain Rose Herbs. Here are direct links to a couple of my favorites, Dried Lavender Flower and Dried Calendula Flowers
