I made stock last night - the usual carcasses, roasted with some tomato paste at 400, then submerged in water with wedged onion, carrot, celery, garlic cloves and boquet garni. I skimmed a time or two, and it simmered for about 7 hours. I cooled it in an icewater sink with two frozen water bottles in the liquid after straining.
Today I go to put the liquid in some cube trays to freeze Julia style except...it's not really liquid. It's like chicken jelly.
I know gelatin is a good thing, but this seems over the top - I had to use a butter knife to skim my ice trays so they would fill evenly.
I'm wondering if my water-to-bones ratio was low - about 1.5 or 2 gallons to a 2 gallon bag of chicken parts. Did I do something wrong? I've made stock 5 or 6 times before but it was never this...gelatinous.
