This is my first post, so please forgive my newbie'ness. I am hoping to start my first really tasty gelatinous stock to make terrine's. Is there any degree of measurement of "reducement"? Or is it just by taste, as in, -however much I would flavor an X amount of liquid with?? I have a very good source in Houston of many different bones and am very familiar with breakdown of animals, just need a little nudging. And, if anyone in Houston or near there needs help with any sourcing I can help with, let me know!
