Why does doubling the meat mixture suddenly turn a tender loaf into a dense, grey brick that releases a cup of liquid fat into the pan? Scaling ground meat preparations requires maintaining the exact ratio of dry binders like oatmeal and crushed crackers to absorb the moisture released from two pounds of chuck and fresh vegetables during baking. When scaling down to a single pound, halve the egg by beating it first and pouring out roughly two tablespoons, ensuring the mixture does not become overly wet and steam rather than brown in the oven.
Incorporating raw chopped zucchini and onions introduces unpredictable water content compared to using drained canned olives or jarred spaghetti sauce. Fresh vegetables will release their internal cellular water at 212 degrees Fahrenheit, potentially dissolving the structural integrity of the loaf if the pan is overcrowded and traps that steam.
