First off, do you know the difference between a broth and a stock?
Broth is made from the reduction of meat and vegetables (Mirepoix).
Stock is made from bones and mirepoix.
There is a distinct difference between the two in both the richness and flavor.
First, gather your ingredients. Gather and cut your mirepoix, carrots, celery, onions (2 parts onion, 1 part celery, and 1 part carrot), and aromatics such as garlic and herbs. For a meat-based stock, you'll need bones.
Next, prepare your ingredients by washing and chopping them into small, even-sized pieces.
To begin the stock-making process, heat a large pot over medium heat. Add a small amount of oil or butter, then sauté the mirepoix until the vegetables soften and release their aromas. This step enhances the depth of flavor in the stock. Once the vegetables are sautéed, it's time to add the washed bones. The bones contain collagen, which breaks down during cooking and gives the stock a rich, silky texture.
Next, cover the ingredients with cold water. The cold water helps extract the flavors slowly, resulting in a flavorful and clear stock. Avoid using hot water, as it can lead to a cloudy stock.
Bring the pot to a simmer, not a boil. Simmering allows the flavors to meld together without making the stock cloudy. Skim off any impurities that rise to the surface, as this will result in a cleaner-tasting stock.
Now, it's time to add the seasonings. You can use herbs like thyme, bay leaves, and parsley, as well as salt and pepper to taste. Be mindful of the amount of salt you add, as it may end up too salty when you use it in other dishes.
Once the stock has simmered to your desired flavor and strength, strain it through a fine-mesh sieve or cheesecloth to remove any solids. Allow the stock to cool before storing it in airtight containers in the refrigerator or freezer.
To fortify the stock even further, after about 1 hour, remove about half the stock. Simmer the remaining stock until it reduces by 1/3, then add back the reserved stock and again, reduce the stock by 1/3. This will provide a much richer taste and color.
