Taking Stock
Three things you need to remember about stock: 1. It is so versatile in the kitchen that it always needs to be on hand and in large quantities. 2. It has to be cooked properly to achieve maximum flavor and clarity. 3. It has to be cooled and stored properly to make sure that none is wasted. Your sauce, soup, starch, vegetable, and even proteins (that you're braising or poaching) depend on you executing each one of these points properly.
There are basically two categories of stock. Those being white stocks and brown stocks. What's the difference you ask? White stocks are made by adding the bones of whatever animal to the liquid without roasting them first...Raw essentially. Brown stocks are always made by roasting the bones before they're added to the liquid. Beyond that stock is made fairly universally using the following steps. Learning to make stock may seem trivial but it takes a long time to perfect it.........and you can taste the difference.
Stock
1 Part Animal Bones (unrest or roasted depending on it use)
1 Part Mirepoix (carrots, celery, onion, leek)
4 Parts Water
Fresh Herbs(thyme, bay leaves, rosemary, mint...Or any combination you wish)
Whole Peppercorns
Cheesecloth
Twine
One of the most important things to conceptualize is that this process will take different amounts of time depending on the bones that your using. For example beef bones are much sturdier than chicken bones therefore it will take longer to produce maximum flavor in a beef stock than it would for chicken. You also need to cut your mirepoix larger if you stock is going to take longer. That's because the smaller your cuts the quicker the stock fluid will extract the vegetable or mirepoix flavor. If the mirepoix in stock is cut too small it will quickly extract all the flavor from the vegetables and make your stock cloudy and bitter. This obviously would have a negative impact on your sauce, soup, etc. ;that the stock is being used for. So all this being said, large chopped mirepoix for sturdier long simmering stock and smaller cuts for quicker stocks.
Begin by filling your stock pot with water. Give the water some heat and bring it to a slow simmer. Now add the mirepoix and bones. The next thing you'll do is take your fairly large piece of cheese cloth, unfold it, and place your herbs and whole peppercorns in the middle. Now, take the corners of the cheese cloth and bring them up to the center and tie off the corners in the center with the twine thereby making a pouch. You want to make sure that you have extra twine coming from the tie so that the pouch can be tied to the handle of your stock pot so it is easy to remove later on. You don't want to go fishing in a huge simmer cauldron of stock for your herb pouch...or as it is called in French, sachet. That's basically it. Let the stock simmer for anywhere from 1 hour to 8 hours, skimming frequently to remove the impurities that are left from the bones and mirepoix. Remember, true stock shouldn't have salt in it as it is the base of most food items that will be seasoned during preparation of that respective item. Also, salt will intensify as food is reduced to intensify flavor. Adding salt to stock essentially makes broth and that isn't what your shooting for here.
Some basic stock time guidelines:
Fish Stock: 1 hour--fish bones are typically tiny and flavor is extracted quickly
Chicken Stock: 4-6 hours--smaller bones which are fairly sturdy
Beef Stock:6-8 hours--large bones need a long time to fully extract flavor
Cooling the stock stock properly is also important. If stock isn't cooled quickly enough it will turn rancid as bacteria will have time to grow to levels where they influence the flavor and potentially make people sick if they were to eat anything prepared with it. When your stock is done place the entire pot in a sink and pack ice around all sides, all the way to the top to cool it from the outside. If you have a ice paddle put it in the middle of the stock to also cool from the inside. It's even ok to use an old two liter bottle that you've filled with water and frozen. Once the stock is ice cold, transfer it to a container and cover with plastic wrap. MAKE SURE IT IS EXTREMELY COLD before you wrap it though because bacteria will thrive if heat is captured in the container with the plastic wrap. As the stock continues to cool the fat from the bone marrow will rise to the top of the stock acting as a seal that helps preserve the stock even longer. It's totally normal so don't worry about it.
Store and use with whatever recipe calls for it.
