When a friend’s husband butchered a few head of cattle and asked if I wanted some of the beef fat for soap-making, I couldn’t pass it up. After two days of slow-rendering the fat, it was time to get started on the soap.

I decided this would be a “clean out the fridge” soap. After canning every ripe tomato from my garden, I still had a ton of green fruits on the vines that likely weren’t going to turn before the first frost. Years ago, I’d made a successful soap using my heirloom tomatoes, so I decided to try another batch using the juice of green tomatoes.

I used green Romas for this formula, but any green tomato will work. After processing the tomatoes in my blender with a bit of added water, I ran the resulting pulp through a fine-mesh sieve to collect the liquid. I added the seeds and pulp to my compost pile.



I like to develop formulas in percentages, because when I share them, it’s easier for others to scale the formula to fit their soap molds. Be sure to run this formula through a soap calculator using the size of your own mold to get the proper lye and liquid measurements (see www.Brambleberry.com/Calculator ). I use a digital kitchen scale when measuring ingredients.

  • Beef tallow: 60 percent
  • Olive oil: 25 percent
  • Unrefined shea butter: 10 percent
  • Castor oil: 5 percent

Additionally, I like to add 1-1/2 percent of the total weight of fats and oils in beeswax. This doesn’t get factored into the total weight of fats and oils, because I treat it as an additive; the beeswax gets added to the fats during the melting stage.
