My recipe calls for .25 ounce package of active dry yeast, and the package of active dry yeast that I purchased from the store is 1/4 ounce packages is this the same amount of active dry yeast that I need for the recipe ?? 
When I render fat scraps (usually taken from brisket and shoulder roast), there is usually a significant amount of connective tissue mixed in (although I try to trim away all of the meat). Thus, after rendering the tallow and letting it cool, the liquid below the tallow is quite gelatinous. It is a whitish color. It is thicker than a typical stock, although not quite as thick as calf's foot jelly. I save this and use it to thicken broths and soups (although it doesn't have much flavor, so I don't use it by itself).
