It's very doubtful it will make you sick. However, the baking powder will be useless in the recipe if it has reached (or surpassed) the expiration date.
To make bread using baking powder instead of yeast, you can use a recipe that includes baking powder as a leavening agent. Baking powder helps the bread rise without the need for yeast. Simply mix the baking powder with the dry ingredients, then add the wet ingredients and bake the bread according to the recipe instructions.
I've run across that a few times, usually less soda than baking powder. Shouldn't be a problem.
I just used some baking soda that is 4 years expired. Did the water test (tsp of soda - add a little water - see if it fizzes) to make sure it was potent. Then went on to use it. I had NO problems baking biscuits with it. Turned out great.
Yes, but one should reduce the amount of salt in the recipe. When one does not have baking soda, it is best to use a cookie recipe that calls for baking powder, because the two ingredients are not identical.
The original Nestlés Toll House cookies (chocolate chip cookies) recipe calls for baking soda, not baking powder. There is no substitute for baking soda or baking powder in a recipe. You have to have it.
If a recipe calls for baking mix, you can use a commercial pre-mixed baking product like Bisquick, or create your own by combining flour, baking powder, salt, and sometimes sugar. Just make sure the ratios match the recipe you are following.
Baking soda is already an ingredient of baking powder so by mixing the two you would be simply changing the proportion of baking soda to baking powder. It will make no real difference to the outcome if you make up the volume of raising agent the recipe calls for with any proportion of baking powder to baking soda. As a safeguard you may like to add a teaspoon of white vinegar or a tablespoon of yoghurt or buttermilk to a cupcake recipe made with baking soda - the acid in the vinegar/yoghurt/buttermilk will react with the Soda to release carbon dioxide which will make you cupcakes rise.
You cannot use baking powder as a substitute for baking soda
To make sugar cookies without using baking powder, you can substitute it with baking soda and cream of tartar. Simply mix 1/4 teaspoon of baking soda with 1/2 teaspoon of cream of tartar for every 1 teaspoon of baking powder called for in the recipe. This will help the cookies rise and achieve a similar texture without the use of baking powder.
Actually, both are activated by moisture( just a fun fact), but they are used under different conditions.Because baking powder contains baking soda. Also because baking soda does not contain the acidity to make a cake rise.
Bicarbonate of soda mixed with cream of tartar (this mixture is essentially what baking powder is comprised of). I believe the ratio is meant to be 1:3 bicarb to cream of tartar to make baking powder. Otherwise, there are no substitutes, but using self-raising flour may help slightly (depending on the recipe).
Baking soda and baking powder are very different in how they work. Think of baking powder as making something more light and fluffy. Baking soda is going to make something taste less sweet and slightly more light. But yes. If your recipe calls for baking soda, or baking powder using the correct amount of both is important. You cannot substitute one for the other.
