I love the way it appeals to all my senses as well as to my scientific side. It's a perfect amalgam of the sensual and the intellectual. It's about how it looks, how it feels on your skin, how it smells, what you put in it and how that might affect the environment. I love every little thing about it from the thinking about a recipe to the technicalities of implementing the idea. I love the look of it as it emulsifies and traces, the anticipation of the cutting, the OCD details of the soap diary, the fun of using something I made out of stuff from the kitchen, the delight of giving it away.
