Ok, I will admit I was a bit lazy in my last question. And
not being a chemist by trade, I was wondering about ph
levels. I was looking at a youtube clip showing a guy
blowing a hard boiled egg out of its shell, not peeling it.
In the clip he stated you should put baking soda in the
water to lower the ph level in the membrane, and thus
making it easier to blow it out. ( I was a bit skeptical ,
but tried it anyway. My original question should have
been a bit clearer, in asking if baking powder can be used
here, versus baking soda. In reading the article, I am
going to assume I could use baking powder, as I didn't
have baking soda on hand. Thank you.

Given that baking soda is a base and not an
acid, adding it will raise, not lower, the pH.
You have it turned around.

From what it sounds like you're trying to do, I
doubt baking powder will produce identical
results.

I couldn't get the egg to blow out, but it did "inflate" the
sack, and it was very easy to remove the shell, and had
no tears in the egg itself... very smooth

I have to check this out... I *hate* peeling hard-boiled eggs!

Baking powder should result in close to neutral pH effect, being a
pretty well balanced mixture of base (baking soda, sodium bicarbonate)
and tartaric acid. Baking soda was probably intended, so as to raise the
pH and modify the membrane.

By the way, imagine my confusion following your questions, when I read
your first entry he
"Ok, I will admit I was a bit lazy in my last question. And
not being a chemist by trade, I was wondering about ph
levels."
Confused, because I missed the "not" !

NO! Baking powder contains acid, usually in the form of cream of tartar
which causes a chemical reaction rendering the alkaline in the baking soda
less powerful.

Back in my Home-Ec days we were taught about the actions of these
ingredients which are- Baking powder recipes act on heat, Baking soda
recipes act on acid.

I think that was an oversimplification although I am sure it's true.

The acid in the powder starts an immediate reaction when mixed with the soda
& liquid. It's the # 1 reason to pre-heat your oven.

baking powder

A LEAVENER containing a combination of baking soda, an acid (such as CREAM
OF TARTAR) and a moisture-absorber (such as cornstarch). When mixed with
liquid, baking powder releases carbon dioxide gas bubbles that cause a bread
or cake to rise. There are three basic kinds of baking powder. The most
common is double-acting, which releases some gas when it becomes wet and the
rest when exposed to oven heat. Single-acting tartrate and phosphate baking
powders (hard to find in most American markets because of the popularity of
double-acting baking powder) release their gases as soon as they're
moistened. Because it's perishable, baking powder should be kept in a cool,
dry place. Always check the date on the bottom of a baking-powder can before
purchasing it. To test if a baking powder still packs a punch, combine 1
teaspoon of it with 1/3 cup hot water. If it bubbles enthusiastically, it's
fine.

It was about as much as most 7th grade girls had patience to learn, I
suppose?
I recall the lecture expanded on it some in warning to not mix up
batters with these agents and let the batter sit around or you'd lose
effectiveness.

Seventh Grade I think we were studying transubstantiation or getting the tar
beat out of us. I forget which

Yes, you hear that about double acting baking powder. It fits with
the theory behind it.

After baking many different products over the years, some right after
mixing and some much later, I've never had a baking powder leavened
product rise any less because of a delay sitting around before cooking.
I conclude from this that most of the leavening action in double
acting baking powder comes from applying heat.

double-acting, which releases some gas when it becomes wet and the rest when
exposed to oven heat. Single-acting tartrate and phosphate baking powders
(hard to find in most American markets because of the popularity of

Yes. I'm familiar with the theoretical part.

What I'm saying is that I've found through experimentation
that most of the leavening action comes from heat side of
the equation.

If one could discount the steam produced in the baking process there might
be a way to verify what you are saying, However if you let a batter rest for
several hours and then bake it I suspect you'll see how it ends up.

I guess pancake batter made fresh and batter from the day before would give
some comparison. I wonder just how stable wet cream of Tartar is.

As a datapoint, I've had quickbread batter sit for well over
an hour while the first round of cakes baked. When the long
sitting batch cooked they were identical in every way to the
ones that were cooked immediately. No loss of leavening.

Interesting.

I don't really know, but I would guess pretty stable. It is often
produced from the lees at the bottom of wine tanks. Those, of course,
are pretty darned wet. If a wine has too much tartaric acid, it
sometimes throws it off while in the bottle. It likes to crystalize on
the bottom of the cork. Of course, that is supposed to be kept pretty
darned wet also. The crystals on the cork are considered a cosmetic
defect, since the flavor is not affected, but people don't like them, so
often that wine is discounted.

my father used to say the nuns would rap the kids on the knuckles with a

the edge, not the flat part.

My father was a senior in high school and taking a physics exam for MIT.
He scored 98. His HS physics teacher cuffed him for not scoring 100.
(he was accepted to MIT anyway...lol) So it wasn't just the nuns, even
the public school teachers could have a lil fun.....
