Baking soda and cream of tartar. Make baking powder

1 tsp baking soda
2 tsp cream of tartar

Thanks, I don’t have cornstarch on hand so I will experiment with adding more lemon juice in order to activate the baking soda.

Thanks, Hélène! Indeed, using less baking soda might do the trick. Here the lemon juice acts as acid, so I think other acid (like vinegar) is not needed.

Make your own baking powder, its just a mixture of baking soda and cornstarch, basically. Google for recipes. You can just leave out the cornstarch if that bothers you. Its just used as a bulking agent, from what I recall.
So in essence, you’d need alot less baking soda. Make sure you use an acid for the baking soda to react with.

Hi Jax, sorry to hear about your bad experience. Obviously baking soda is not a good option for these muffins, thanks for trying it anyway. I doubt adding spices would help, that first came into my mind. I guess the metallic (or cleaning product) taste cannot be covered. I wonder if anybody has any other suggestions?

Hi Elviira,
I tried the muffins today with equal amount of baking soda instead of baking powder. I also left out the lemon pieces since I only have lemon juice and used erythritol that wasn’t in a powdered form.

Long story short, they came out really bad 🙁 It tasted like I was eating a cleaning product! I suspect that it was the baking soda since there was a little bit of a metallic taste. They otherwise rose well, had nice texture and held together better than most muffins when I cut them open. So much for neutralization from the lemon juice.

I only cooked half of the batter. Any suggestions on what I can add to save the rest of it? I don’t have baking powder and don’t plan on buying any just for half a recipe. Otherwise, I’m just going to throw out the remaining batter.

Hi Jax, baking soda should work, the acid lemon juice helps rising so there is no need to use vinegar. If you try that, please let me know how the muffins turned out!

And is it also okay to just use lemon juice?

Thanks in advance 🙂

So sorry to hear that the result wasn’t satisfying. Hmm, sounds that there was too much coconut flour. The tablespoons should be loosely scooped, not packed. If you weigh it, it should be 37 grams (1.3 oz). Hope this helps!
