Hi Amal, I’m so happy to hear you like the book! :)
I’ve never tried laurel leaves to infuse soap, but I think you could definitely try it out!
I would infuse olive oil with laurel leaves (just like the calendula flowers in this article)
and then make a small test batch using that infused oil:

Then you’ll be able to see how you like it.
If you give it a try, let us know how it goes!
Happy soapmaking!
