  • Why it's better to grind meat semi-frozen

    just answered a pm from lynsey, figured I might as well post it up as well :-)

    HI CA hope everything is good with you.

    I have a question, what is the advantage of grinding your meat while frozen or is there one.

    Thanks Herb
    several advantages. It cuts cleaner, the fat doesn't smear. You don't get that horrible build up of sinew around the cutting blade and clogging the grinder plate up, because it cuts rather than pulls.
    Because the meat is still quite fragile when you mix it, the chunks of muscle break down further into smaller muscle fibres. So you can get away with one grind using medium or large plate and a good mix and end up with an almost emulsified texture sausage without having to resort to a food mixer or a double grind.

    You also get significantly less back pressure in the grinder which extends the life of your grinder and helps keep the meat cool.
    Some commercial sausages are deliberately 'cooked' by pressure in a feeder rather than by applying direct heat.

    Plus you can take the whole process that bit slower and more relaxed without having to worry about whether or not the meat's too warm.

    And when you add the spice slurry and mix the temperature actually drops.

    Did a mix the other day. The meat started out at -1 (centigrade), was -0.5 after the grind and dropped down to -2 after spice and beer slurry and mixing.
    It's the old adding salt to ice trick.
    But for safety having your sausage meat end up colder after grinding and mixing has to be good

    It does mean you have to add the spices after grinding, but once you get into the hang of it, it is a better system.

    I find the best way to get the meat temp just right is to use the microwave at it's lowest setting - NOT DEFROST.
    I reckon 5-10 minutes per pound if using shoulder steaks/csr's.
    If you plannig on using whole butts, then I'd buy fresh, debone and slice AND then freeze. makes for much more even defrosting.

    The ideal state for the meat is when it still feels frozen but you can slice it fairly easily with a good knife.

      I've also heard that it's a good idea to freeze your grinder body and feed tray, if you have the room. I have no idea on how other grinders are constructed but looking at mine, I couln't see how it could hurt. Where ever I heard it from, said the actual grinding friction heats up the grinder body on really long grinds. Mine is so oversized, it never has a chance to warm up, but I freeze it anyways.

        Nice informative post CA. I've known people to freeze their grinders, but I do small batches of sausage and heat is not an issue.

            I find that the bowls I use (very thin, very cheap SS), take up the cold from the meat and end up with ice on the outside.

            Likewise I think that the metal grinder parts will be cooled down by grinding - what is essentially - ice.
            So If you are grinding semi-frozen meat then I don't think it's necessary to bugger around with the grinder parts. They'll be cooled by the meat passing through. Plus you get less back pressure, so the motor doesn't work as hard and pass heat on to the working end of the machine.
            IT grinds faster as well so the machine is running for less time.

            If you're grinding fully defrosted meat straight from the store or fridge - then I guess it wouldn't hurt.

              Great info Alex. It's very important to keep everything as cold as you can. The longer you stay under 40 degrees, the bigger the window is for cooking or smoking.
              I use my band saw sometimes and cut frozen strips for grinding. My stainless bowls also get frost on the outside after I've ground frozen meat.
