Where can one buy food grade cornstarch & calcium phosphate?
I bought a ton of Baking Soda at Costco (sodium bicarbonate), and I want to make a small amount of baking powder.
Baking powder, as far as I can tell, is baking soda + cornstarch + "cream of tartar" which is usually either calcium phosphate or potassium hydrogen tartrate (KC4H5O6).
I went to Safeway, Trader Joes, and Whole Foods, but none had the missing ingredients, only one of which is required (the cornstarch is optional but the acid tartrate is not.

So is cream of Tartar, but if I remember right is seems to cost a fortune for what it is, and is sold in small amounts. Maybe Smart & Final or Restaurant Depot, etc. sells in larger quantities for a more reasonable price.
Yahbut he only wants to amke "a small amoun of baking powder".
Most folks would just buy a can of baking powder but If price is no object there's a recipe or DIY baking powder here:

"Optionally, you may create and store a powdered baking powder substitute for use at a later date. Combine your cream of tartar and baking soda in a 2:1 ratio as you normally would, then add a quantity of cornstarch equal to the amount of baking soda you added. The cornstarch will absorb moisture from the air, preventing the baking soda and cream of tartar from reacting prematurely."

Some of us would simplify that to combine your cream of tartar, baking soda , and cornstarch in a ratio of 2:1:1
Think of all the cumulative time I've saved the folks of the world with tha t.
I just buy Argo at Albertson's Supermarket. It's on the shelf right next to the cornstarch :)

Clabber Girl bought the Rumford label and it's aluminum free too but slightly more expensive than Argo.
As for cream of tartar, I wouldn't call them health foods stores exactly, but a couple of local markets have bulk spices that a much less expensive than those little McCormick jars. Of course, they have bulk baking powder too. And cornstarch.
Then you must be blind. Any Safeway or Whole Foods will have both those items. Safeway even has their own house brand of cornstarch and Whole Foods has their own 365 brand of Cream of Tartar.
Juile, is that you?
Nothing more to see here. It's just another time-waster.
There is a huge difference in the taste of fresh baked bread and cake versus store bought, that's why I bake some stuff here. There isn't any taste difference in baking soda bought or made.
See above.
See above.
Sure, 99% of it goes into the pool.
To use you logic, why don't you buy the wheat to make the flour too? Almost everyone I know does at least some baking, cooking, etc. I don't know anyone that makes their own cream of tartar, much less in 5 lb quantities. You think maybe that's why the supermarket doesn;t carry that size?
And for the record, you didn't say you wanted a 5 pound bag of cream of tartar. If you had, none of us would say to look in the local supermarket. You said you couldn't find it at all in the supermarket. All the rest of us have found it, it's in the spice rack, in a little jar. costs ~$4. You can buy 10 times as much *baking powder*, already made, at the same store for less. It performs the same as what you're going to make, so there goes all the bogus food comparisons you made above.
Also, if you use that much, then you can buy *baking powder* in bulk. A simple google search shows it's available for as little as $7 for a
5lb bag. A similar search shows that cream of tartar is also available for ~$7 a pound from various suppliers. What exactly is your problem?
Something is obviously not right here. Someone who would need that much baking powder, cream of tartar, etc to make screwing around worth it, surely knows where to find all those products in the local supermarkets. And enough sense to know that if you want bulk volumes of them, you can find them at restaurant supply stores, online, etc. What buffoon would expect to find 5lb bags of cream of tartar in a supermarket?
