Several years ago, when I went to make my dairy-free, egg-less chocolate cake recipe, I discovered I was out of baking soda. (The recipe called for baking soda and red cider vinegar.) I looked online to find the substitution measurement of baking powder vs. baking soda so I could use what I had on hand in the kitchen: baking powder.
On a cooking site (forgive me, I’m not sure which one it was), they recommend using 3 tsp. of baking powder to replace the 1 tsp. of baking soda (minus the vinegar).
Okay, fine. Skip ahead to one or two years ago, I was running low on baking powder. I only had 2 tsp. of baking powder left. My desire for cake won out and I used the 2 tsp. and baked the cake anyway. I thought I’d just have a denser cake, which was fine by me. It would still taste just as good. 🙂
‘Lo and behold!! My cake was as high, if not a little higher with only 2 tsp. of baking powder versus the 3 tsp. I’ve used all this time! I was pleasantly surprised!
Why? For two reasons. 1) This meant my baking powder would last longer, and 2) It decreased the amount of sodium in the cake. (We’re being careful about how much sodium we’re using in our diets.)
55 mg of sodium per 1/8 tsp. = 440 mg of sodium per 1 tsp.
I was using 3 tsps. so…3 x 440 = 1320 mg sodium for a single-layer 9-inch cake!
Granted, you don’t eat one entire cake in one sitting but still, that’s a lot of sodium. I broke that down to 220 mg per slice out of 6 generous slices, (remember, it’s only a one layer cake).
Versus: 2 x 440 = 880 mg sodium. That’s about 147 mg of sodium per slice using the 6 generous slices example.
Now for the fun, money-saving part!
The container says there are 383 servings per container. Remember, the servings are 1/8 tsp., so 383 divided by 8 = 47.875 or about 48 tsps. of baking powder per container. If you use 3 tsps. each time, you get 16 single-layer cake uses out of one container.
However…if you use 2 tsps. each time, you get to bake 24 single-layer cakes instead of 16 out of the same amount of baking powder from the same container!!! 🙂 Woo-hoo! 8 more cakes before I need to buy another container of baking powder!
In times like these, I’ll take that savings! 🙂 LOL Life’s simplest pleasures.
