I was getting everything made late last night to do a meatloaf this afternoon but may change schedule to tomorrow instead. I already mixed in the raw egg, breadcrumbs, thawed sirloin, fresh ground pork, fresh "meatloaf" mix (beef/pork/veal), some homemade canned salsa, and fried finely chopped onions/peppers/mushrooms. I shaped it and added about 5 slices of bacon down the top, and it's currently in a foil baking tin, in the fridge. Estimate is between 3.5 & 4.5 lbs. I highlighted the sirloin because there was a sale on it as a "peeled knuckle" sirloin (never heard of that) that was cheaper to buy myself & grind it; I did, and I did grind it, used some for burgers & tacos, then after a couple days froze the rest. That was a couple weeks ago and then removed from freezer & let it thaw in the fridge yesterday. All the other meats I just bought Tuesday, if it matters, and were stored in the fridge, top shelf/rear, just below the freezer (coldest part of my fridge section.) Is there any reason, with any of these ingredients, that I couldn't keep it in the fridge for another day or so? The raw egg? the previously frozen beef? Thanks.
