Subbing Baking Powder for Baking Soda in This Recipe
I want to make some rice/lentil pancakes. The recipe calls for (sorry for the odd cut and paste):
cups white basmati rice or
long-grain white rice, rinsedand drained
cup urad dal (ivory lentils) or red lentils, rinsed and drained
1 tsp. salt
'/« cup plain low-fat yogurt
'4 tsp. baking soda
1 cup fresh or frozen peas
1 small red onion, minced (1 cup)
3 jalapeño chiles, stemmed, seeded, and finely chopped
cup chopped cilantro
Melted coconut oil or ghee for greasing skillet
I don't bake (EVER) and don't feel like buying baking soda, but I do have some unopened baking powder (God knows why...). The Kraft website says that you can substitute double the amount of baking powder for baking soda, if you replace the acidic ingredient in the recipe with a non-acidic ingredient. What would be the acidic ingredient here?
The baking powder I have is baking soda plus some other ingredients that make it "double acting" (check the ingredients label on yours). Since there are other ingredients, it's not as concentrated as baking soda alone.
The yogurt is the only acidic ingredient of note. Personally I don't find baking powder or soda make much difference when there's no glutinous dough to hold bubbles, so I don't think it will make much difference what you use or don't use. In fact, this recipe looks more like a very wet pilaf than pancakes (not that there's anything wrong with wet pilaf). Do you blend it up first? Maybe that would make sense, but otherwise you're making fritters.
So use baking powder. Couldn't hurt.
Both are leaveners - baking powder is primarly baking soda and cream of tartar - and if you have that familiar yellow and brown canister from Magic, then cornstarch too. If anything I'd think theyd be more crisp... but the resident kitchen chemists could probably explain it better. I'd think in this case you can make the substiution but if you do go buy some arm & hammer there are a multitude of uses for the stuff so it wouldn't be a waste.
Joy of Baking has a good primer on baking soda vs powder: http://www.joyofbaking.com/bakingsoda...
Don't mix your baking soda with vinegar (unless you are making a volcano for a school project). Vinegar, an acid, will neutralize the baking soda which is a base. What makes baking soda an effective cleaner is that it is moderately alkaline (basic). This is especially useful for breaking up greasy/oily residue. Mix some up in plain water and use in a spray bottle for light cleaning. For tougher jobs you can make a thick paste of baking soda, coarse salt and water and use it with a scouring pad.
The volcano comment was meant to be slightly humorous; I guess I missed the mark. Of course quick breads or other chemically leavened baked goods mix baking soda and an acid together to create carbon dioxide thus raising the batter.
I was addressing the use of baking soda as a cleaning agent. You don't want to react the baking soda with an acid if you intend to use it as a cleaning agent.
