Getting the Proportions Right for Tallow-Based Homemade Soap

Scalloped Top Homemade Soap Bars

I love this time of year. The garden is reaching its summer end and you have to start getting creative on how you can use up your surplus so nothing goes to waste. A friend of my husband’s recently butchered a few head of cattle and asked if I wanted some of the beef fat for soap-making. There was no way I was going to pass up the free fat, and after two days of rendering, it was time to get to work on the soap.

My apothecary cabinet was getting pretty full and I needed to make room for new infusions, so I decided this would be a “clean out the fridge” type of soap. I had a bumper crop of tomatoes this summer, too. After canning every red tomato from my garden, I still had a ton of green tomatoes on the vines that I knew more than likely weren’t going to turn this season. I picked all that I could before the frost got hold of them, made salsa verde, and gave even more away to friends. I had made a very successful bar of soap years ago using my heirloom tomatoes and decided to try a batch using the juice of the green tomatoes as the liquid in this batch of soap.

Juicing the Tomatoes

I used green roma tomatoes for this formula but any green tomato will work. You don’t want seeds or any added tomato pulp in your soap so after blending the tomatoes in my blender with a little bit of water to get the blender going, I ran the liquid through a fine mesh sieve to remove the seeds and pulp. I added this to my compost pile (the chickens loved it!) so nothing went to waste.

Cleaning Out the Apothecary

I’m not sure about you, but I have an abundance of infused oils in my apothecary cabinet this time of year. And to be honest, they were probably past their prime. The oils hadn’t gone rancid by any means, but they were at the point where they were at risk of needing to be discarded if I didn’t do something with them soon. After the growing season, I have fresh plants and herbs that will need to be infused, so it was time to get out with the old and in with the new.



A big batch of soap is just the right way to use the oils up so nothing goes to waste. In this batch I used: lavender-infused olive oil, wild rose-infused olive oil, juniper berry-infused olive oil, and red clover-infused olive oil.
