Displaying items by tag: sous vide

    A sous vide machine is something that may seem excessive or complicated at first but well worth the investment. I honestly think is one of the greatest things to have for a reasonably serious cheese maker. If you make cheese, you don't want to over shoot, or drop below desired temperatures, frantically adjust, then forget an important step, all because you're stuck trying to control the temperature of your milk. Imagine how much more time consuming it gets when you make two or even three types of cheeses all at once. With sous vide devices in place, you simply set it up, turn it on, and get on with the actual cheese making.

    Star Wars and bad puns...

    I don't know if anyone particularly cares about "Star Wars Day" (which for people who haven't a clue, is "May 4th"). It comes from the Star Wars quote:

    "May the force be with you" (just exchange the word "force" for "fourth")

    However, being a bit of a nerd myself, with that pesky I.T./Scientific Instruments/Drone company career, years upon years working in academia, and living on campus for over a decade (as a staff member) I really didn't have much chance in nerdiness stakes.

    So how do I celebrate a fictional holiday for a fictional story? No, not buy buying a light sabre. Although, I decided I'd buy something that's shiny, somewhat cylindrical, and capable of burning flesh, and that is....

    By literally buying my fourth, sous vide machine on May 4th. To increase my functional cheese making capacity (factually) by a third over my previous capability.

    Sounds almost like a tongue twister, doesn't it?

    Sous Vide Explained:

    It has come to my attention that I really haven't given much explanation about what a sous vide is. Sous vide is a french term (Pronounced "Sue-veed") that translates as "under vacuum". It's a rather unusual way to cook things, that is becoming very popular of late.

    The general gist is this. You stick a piece of raw meat (maybe with some herbs, spices and/or butter) in a vacuum sealed bag. Then put that bag in a bath of water and cook it in extra low temperatures (generally somewhere between 51-90C (or 125-199F) for a very long time.

    If barbecuing "low and slow" (low temperatures for a long time) produces a more tender meat at 110-120 degrees Celsius, (compared to higher temperatures), then sous vide takes this to a whole new level. In some ways, it goes beyond slow cooking. So if you want your meat to disintegrate into flavoursome tenderness on contact with your tongue, this is probably the way to go.

    While the meat is cooked to delicate perfection, the down side of this is that you don't get that browned "bark" in your meat, so sous vide steaks are often seared with a hot pan for a few seconds after cooking to get that delicious, almost charred effect. Also, you won't get any "smokey" flavour.. because nothing really got that hot in the first place.

    If you're wondering... "Aren't we in the cheese making section?"

    Well I use my sous vide machines somewhat differently, in that I use them to control the temperature when making cheeses.

    When I first learned to make cheese, the instructor assumed that everyone would have a very basic setup. Namely, a boiling pot full of water. If you are managing your temperature manually, when the bath water cooled down, you'd scoop water from the boiling pot into the bath to increase the temperature, and then scoop some of the cold water and put it back into the pot to minimise waste/stop overflowing.

    It works, but it requires constant monitoring. You'll literally spend all day, scooping water from the pot, to the bath, and back again. If you've got several cheeses to make, you really can't manage several vat temperatures all at once and still make that many cheeses without help.

    By using a sous vide machine, I can just set the temperature I want for each bath, and let it do the rest. Once you have one machine, you'll never want to go back to the manual control method.

    Sometimes I like to make a few different cheeses (each needing a different temperature) I'll run several vats with their corresponding sous vide machine controlling that temperature. Other times, I want to make a lot of the same cheese, then I need to run multiple vats with multiple machines at the same temperature to ferment an appropriate amount of milk.

    Other times, if the stove is busy, I'll stick 2 or even 3 sous vide machines into the one vat to rapidly increase the temperature of my water bath. This can be very handy when making cheeses that involve cooking the curds. You need the milk temperature to rise by roughly 1-2 degrees Celsius per minute, and that gets hard for larger vats of milk. However, the stove and a very large saucepan/stock pot is still going to be a better method for rapid heating.

    Anyway, when this fourth one arrived at my door step, I was a little surprised when I opened it. The plug was clearly not designed for Australia. This particular one was a 220V model, but came with a European plug. You can get an adaptor, but when I have so many fluids around, I prefer to use an appropriate power plug, so my plan for May 6th or for another Star Wars pun, "Revenge of the Sixth" I got the plug converted "to the dark side" (white adaptor to black Australian plug).

    Now it works really well!

    So if I use four, 12L vats to culture my cheeses, heated by four sous vide machines. I can handle up to 48L of milk in any given session. Depending on the type of cheese(s) made, I can get a yield of 3.5-5Kg of a low-yield cheese like Parmesan, or up to 7Kg of Brie, perhaps somewhere around 10-12Kg of "fresh" cheeses like cottage or cream cheese.

    I have no idea what I would do with 10+Kg of cottage cheese... I'm more likely to make Parmesan, Halloumi, Cheddar and a small amount of Quark all at once. Simply because they stagger the finished time well, and can be used in a variety of differing meals.

    Anyway, I hope you are safe and well out there! I think I need to plan my next cheese making session!
