Baking soda can be used instead of baking powder, but only together with an acid and in a smaller amount.
For a batter like charlotte, the right substitution will help the cake rise, while the wrong one can leave a sharp "soapy" aftertaste.
Baking powder and baking soda serve a similar function: they create carbon dioxide bubbles that make baked goods light and airy. However, they are not identical ingredients. Baking powder already contains baking soda, an acidic component, and a little starch. Baking soda, by contrast, needs an acid to trigger the reaction. So substitution is possible, but it should be done carefully, not relying only on apples or chance.
What to use instead of one teaspoon of baking powder
Instead of 1 teaspoon of baking powder, people usually use about 1/2 teaspoon of baking soda. An acid must be added to the baking soda: roughly 1 teaspoon of lemon juice or 9% vinegar. If the recipe already contains kefir, plain yogurt, sour cream, soured milk, lemon juice, natural cocoa, or another acidic ingredient, the baking soda may react with that instead.
For a simple apple charlotte with a neutral batter, the easiest option is to add 1/2 teaspoon of baking soda and 1 teaspoon of lemon juice. The baking soda can be mixed with the flour, and the lemon juice can be added to the liquid ingredients. Another option is to quickly neutralize the baking soda with the juice in a spoon and immediately add the mixture to the batter. After that, do not wait long: the pan should go into a preheated oven, because the reaction begins at once.
Why apples alone are often not enough
Tart apples do contain organic acids, but their amount and acidity are unpredictable. One variety may contain enough acid for a partial reaction, while another may not. If the baking soda is not neutralized, the batter develops an unpleasant alkaline taste, and the crumb may sometimes become darker in color.
It is not worth increasing the amount of baking soda so the cake will "rise better." Too much will not make the baked goods fluffier, but it can spoil the taste and texture. In cooking, as in other daily decisions, moderation and responsibility are valuable.
"All things are lawful for me, but not all things are helpful; all things are lawful for me, but I will not be brought under the power of any." 1 Cor 6:12
This principle is not a baking recipe, but it reminds us that usefulness and moderation matter even in small household choices. A tasty dessert does not require an excess of baking soda, sugar, or fat.
How to mix the ingredients correctly
If the acid is kefir, sour cream, or yogurt, it is better to mix the baking soda with the sifted flour first, and then quickly combine the dry mixture with the liquid one. If lemon juice or vinegar is used, it can be added to the eggs or another liquid part of the batter. There is no need to beat the mixture for a long time after adding the baking soda: the gas bubbles should remain in the batter, not escape while still in the bowl.
It is also important to check whether the baking soda is fresh. If it has been left open for a long time in a damp place, its effect may weaken. A small test is simple: a pinch of baking soda in lemon juice should fizz actively. If the reaction is barely noticeable, it is better to use a fresh product.
Simplicity and a healthy approach to home baking
The Adventist view of health does not require giving up every homemade pastry, but it encourages wise choices. Ellen G. White, in her counsel on diet, emphasized simple, nourishing food, cleanliness, moderation, and avoiding what harms the body. Homemade charlotte can be made more simply: with less sugar, some whole-grain flour, plenty of apples, and without unnecessary additives.
"Therefore, whether you eat or drink, or whatever you do, do all to the glory of God!" 1 Cor 10:31
To glorify God in eating does not mean becoming anxious over every crumb, but showing gratitude, moderation, and care for those for whom we prepare food. It is especially important to consider the needs of children, people with allergies, or those whose doctor has advised them to limit sugar or certain foods.
Practical application
If the recipe does not have baking powder, for 1 teaspoon use 1/2 teaspoon of baking soda and 1 teaspoon of lemon juice or vinegar; after mixing, bake immediately. For your next charlotte, try reducing the sugar by one or two spoonfuls, adding more apples, and serving it as a simple homemade dessert prepared with gratitude and moderation.
