we're talking science. Or, at least, I am. We're talking REAL numbers, not some airy-fairy
POETIC LICENSE.
Deal with the real numbers in both the recipe and the butter. Then it begins to mean something. Your
silly, self-serving "example" is apparently all you have. Poor JimLane.
Quoted message said:Bob put up a recipe that calls for unsalted butter and this recipe ends up having, for grins, 100
units of salt in it. Whoops, no unsalted, so we'll add some salted butter in (btw, let's not get
into "adjusting" because the other salt is already in). Say there is enough salt in the butter
added to bring the overall salt content up five units.
Here's the real information, JimLane. Why not use it? No need for you to strain your pretty little
head making up stuff.
<<<<<<<<<<< begin quote >>>>>>>>>>> The cakes each took 2 tablespoons butter, 5 eggs, 3/4
cup of flour,
1/4 cup milk, 3/4 cup sugar, teaspoon baking powder, 1/8 teaspoon salt, teaspoon lemon extract. The
butter (if I had measured it exactly) contained 0.45 grams of salt (28 grams are an ounce), 1/62nd
of an ounce or 0.08 teaspoons of butter. Eight hundredths of a teaspoon. Less than 1/10th of a
teaspoon. That's a Scroogy pinch for a whole cake intended to serve 8. Combining 1/8 teaspoon salt
the recipe calls for with the 1/12th teaspoon from the butter makes the amount of salt leap from
3/24 of a teaspoon to 5/24 of a teaspoon. All the way up to just under 1/5 of a teaspoon in a 9-
inch cake. <<<<<<<<<< end quote >>>>>>>>>>>>
Quoted message said:Bob says that will wash out and doesn't make any difference, because that 5% is inconsequential
(remember, the actual number here is for illustration).
Bob says that adding 0.08 of a teaspoon of salt in a 9-inch cake would be undetectable except to
laboratory instruments. Stick that no-basis-in-reality 5% where you store all your other "facts."
Why use fake numbers when the real ones were given to you? How sad a show.
Quoted message said:Here's the rub, Bob, there is an assumption everyone would make the dish with 100 units of salt.
Not so. People on salt-restricted diets or those who naturally eat low levels of salt might only
put in 25 units. Now that extra five is a 20% increase and that is significant and detectable.
You know, I believe that you don't know how to read the citation I gave you. Why are you talking in
abstract "units" when the absolute numbers are there for you to use? That 5% is significant *only*
as a percent increase. It's *only* significant as an abstract numerical concept.
But, anyway, We don't perceive % increases, we perceive absolute amounts. Your preposterous
"example" is like saying that if I have $5 and you give me $1, that's more "detectable" than if I
have $100 and you give me $19.
So if you actually read the full paper I cited, there's a buncha of NUMBERS and CHARTS and
CONCLUSIONS. Unlike your "citation."
Quoted message said:Here's why (I went out and found some actual real research, Bob, that is replicable and not
meaningless numbers).
"Meaningless numbers" to someone who doesn't know how to interpret them. But that's why I also
posted what they meant. To spare you all that pesky thinking.
I don't see *any* numbers from you here. I see you "interpreting" a paper that you offer no quotes
from, no access to, and haven't even read all the way through, by your own admission. Is this how
you deal with professional citations in your work?
You've attacked me for not offering data and say that in your field, just making statements without
support is bad. You're doing exactly that. I believe that you aren't a technical person and you
certainly aren't a scientist. You certainly don't know how to present data.

Now, I haven't read the full document, but if I get the gist
Gist this. I love "haven't read the full document, but..." Couldn't even offer a URL? Right. Very
credible. I searched for the paper for about 5 minutes and didn't come up with it. The title got
nothing. The author got nothing. Keywords didn't come up with it, either. I'd be very interested in
reading it.
Remember this that I've posted twice to you?
<<<<<<<<<<<< begin quote >>>>>>>>> And here's some honest-to-god science with statistics and charts
and technical terms like "moles' and other cool stuff. <http://lib.tmd.ac.jp/jmd/5001/14_ohno.pdf>
Look at the concentrations of saline solutions that were undetectable. See the pretty lines in the
perceptivity charts. Based on their conclusions, you'll want to forego brushing your tongue before
eating. Dentures won't matter for salinity, only bitterness. These were elderly subjects with
reduced sensitivity from what they should have been able to perceive when younger. But the mean
thresholds of perceptivity is rather higher than I would have thought.
Here's what a molar solution is about <http://www.public.iastate.edu/~bkh/teaching/molarity.pdf>
A molar solution of salt would be 58.44 grams of salt in enough liquid to make a liter. How much
salt was in each solution? Well, to quote myself, "A tablespoon of table salt weighs right at 0.6
ounces or 16.8 grams. A tablespoon is 3 teaspoons of salt which weigh 5.6 grams each."
1= 0.0008 M solution = 0.047 g 2= 0.0017 = 0.099 g 3= 0.0033 = 0.193 g 4= 0.0067 = 0.392 g 5= 0.0134
= 0.783 g 6= 0.0267 = 1.560 g 7= 0.0535 = 3.127 g
Note the mean thresholds for perceiving salinity on page 4. Do the math. Are we done with this now?
<<<<<<<<<<<<< end quote >>>>>>>>>>>>>
Perhaps you noted that the mean thresholds of perceptivity were up at solution 7. When people first
noticed that there was any salt at all. And that was in plain water with no obscuring other flavors
as would be in the cake, particularly sugar and starch.
Here's another way of looking at it: The cake weighs in at about 630 g +/-. The salt was increased
by 0.45 g. or a factor of 0.0007 or 0.07%, all but impossible to detect as a differential. And even
with both salt additions included, the total percentage of salt in the recipe is at 0.0018 or 0.18
percent. That scales out at a hair over the concentration in solution 6.
Quoted message said:of what she says, people who are on low sodium diets, prefer significantly less salt and showed
significant changes in their salt taste (variables) and showed a preference for significantly
lower concentrations of (salt).
Now, I haven't read the whole thing, but is appears that science and replicable research back my
position that the shift from unsalted to salted butter in a recipe CAN make a difference in taste.
As opposed to your, no way.
Hopefully, this will add some new information for you to consider. instead of blindly rejecting
the possibility that a mere change from unsalted to salted butter can make a difference.
Either you're illiterate or deliberately being obtuse. Perhaps both.
I predicted that in using salted versus unsalted butter, any difference would be undetectable in the
quantities at hand. A dozen people tasted both cakes and confirmed that hypothesis. Period.
I also cited a study that dealt with thresholds of perceptivity and offered quotes from it. You can
jump up and down and flap your arms all you want with your hypothetical numbers and obscure papers
you only claim to have half-read, but you've shown nothing. You're offering only your opinions,
exactly as you chastised me for doing. I've brought reference materials. See how it's done?
Here's 5 bucks, JimLane. Buy yourself something frilly.
