Soup Begins with a Great Broth or Stock

Let's start with the words 'stock' which is often
used interchangeably with the word 'broth'. To make stock you only need two
basic ingredients; water and bones... lots and lots of bones. Save the good pieces of meat for later; they go in the actual soup, not the stock. Broth is basically water that's had boney pieces of meat and some aromatic vegetables cooked in it. After all those bits and pieces have given up all their tasty goodness, they are removed and -- voila! -- you've got a great tasting stock or broth for the foundation of your next soup.

The best quality broth will gell and become firm and solid when chilled. If your stock doesn't set up, don't worry, if you're happy with the flavor, then your soup will still taste wonderful... so enjoy.

The best meat stock uses shanks or neck bones from beef, pork, veal, lamb, or game, which are generally very, very cheap and yield unequal flavor for the buck. Another good cut of beef are oxtails which are crosscut and look like little bitty versions of the shank. Chicken, beef and pork feet are other popular cuts for making good tasting stocks.
Consider smoked or cured meats too. Smoked meats come in a wide variety of wonderful choices to add much needed taste to bland foods like dried beans. There are many good goices like pigs feet, hocks, neck bones, or turkey wings and legs, all of these make an excellent soup base.
For poultry base, use necks, backs and the wing tips, and chicken feet , and don't forget the carcass. Cooks in the know, prize chicken bones for their stock, and the carcass left over from a routisserie roast is just as -- if not better! -- than the one you roast at home.
You can also take a lesson from frugal cooks and collect and freeze meat scraps and bones for a nearly free stock or broth. Whatever your choice, look for what's inexpensive or on sale when selecting your next stock or broth makin's.

What's All the Fuss About Browning?
|
|
There are recipes for white
stock and brown veal stock. The brown stocks are made with browned or roasted bones and meat, the
white stocks are made with uncooked bones and meat. I like to start with browned meat because for my tastes, it produces a better flavoredbroth than un-browned meats.
Salt the meat. The salt is going to add flavor and it's going to coax up some protein laden juices that are hiding just under the surface. Once they are up on the surface, they can take part in the Maillard Reaction, which is responsible for browning... and browning equals great flavor, taste and aroma. Small quantities of meat and bones can be browned in the pressure cooker, but a heavy skillet is more practicle for larger amounts. For big bones and bulkier pieces, they will get browned easier in a oven.
Once the meat has browned, everything is put in the pressure cooker. Don't forget to add the lovely, stuck on browned bits and any meat juices to the pot. After cooking, you may
notice a foamy scum has accumulated on
top of your stock or broth. Don't worry, it's just protein and if you are a purist you can skim it off, otherwise leave it as is.
After cooking, strain your broth or stock, it's the rich liquid that's important, so all the solids can be discarded. If someone gifted you
with one of those fancy, cone shaped, wire mesh strainers
the French call a chinois, this is the time to use it. Unless you got one as a gift, however, don't
run out and buy one because normally these
go for anywhere from $60 to $90. Instead
use a 90¢ piece of cheese cloth to line the colander
and slowly pour your broth or stock through the cheesecloth.
Nice
and slow is the key. the liquid is probably going to take a few minutes to work its way through, but that's going to get all of that particulate matter out so the liquid soup base will be nice and clear. Don't push or mash on the solids as it will make the liquid cloudy, not a big deal, but there's no taste left in the solid matter after pressure cooking, so you don't really gain anything by trying to squeeze the last drops out of them.
Skim off the fat from the base before using in your soup, or refrigerate it overnight and then simply
lift off the solid layer of fat in the morning.
Once chilled, you should see a rich, gelatinous liquid that has great body. At this stage you can use the liquid immediately in soups, stews, chilies, grains, rice or dried beans, or portion it out and freeze it for later use.

The
Maillard reaction occurs
when the proteins
on the surface of the
meat recombine with
the sugars present.
The combination creates
the "meaty"
flavor and changes the
color. For this reason,
it is also called the
browning reaction.
The Maillard reaction
occurs most readily
at around 300° F to
500° F. When meat is
cooked, the outside
reaches a higher temperature
than the inside, triggering
the Maillard reaction
and creating the strongest
flavors on the surface.
In the early twentieth
century, Louis-Camille
Maillard happened upon
what came to be known
as the Maillard reaction
when he was trying to
figure out how amino
acids linked up to form
proteins. He discovered
that when he heated
sugars and amino acids
together, the mixture
slowly turned brown.
It was not until
the 1940s that people
noticed a connection
between the browning
reaction and flavor.
World War II soldiers
were complaining about
their powdered eggs
turning brown and developing
unappealing flavors.
After many studies done
in laboratories, scientists
figured out that the
unappetizing tastes
were coming from the
browning reaction. Even
though the eggs were
stored at room temperature,
the concentration of
amino acids and sugars
in the dehydrated mix
was high enough to produce
a reaction. Most of
the research done in
the 1940s and 1950s
centered around preventing
this reaction. Eventually,
however, scientists
discovered the role
the Maillard reaction
plays in creating flavors
and aromas. For example,
as many as six hundred
components have been
identified in the aroma
of browned beef.

Sugar,
used in the right proportion,
can help cut the edge
off other flavors. This
approach can be tricky,
though. You're not actually
covering flavors, you're
adding more flavors
to distract your tongue
from the one you want
to be less prominent.
Getting the right flavor
balance depends on the
ingredients and their
proportions in your
soup. If the proportion
of salt to sugar is
too small, they'll actually
enhance each other.
So you want to add enough
sugar to cut the salt,
but not so much that
it makes the soup sweet.
You might want to practice
this one before putting
it to use. The reverse
of this is also true:
Bitter, sour, and salty
tastes can lower the
intensity of sugar.
Keep this relationship
in mind when checking
the labels on processed
foods: Sugar and salt
are often used to cover
less-pleasant flavors
that arise when food
is processed. Processed
foods often contain
much more sugar and
salt than your palate
can detect, and often
more than is necessary
to balance flavors.
