Previously: Thermophilic vs. Mesophilic Yogurt Making

I boiled a gallon of milk in an Instant Pot. I let it cool to about 98°F, and then added the filmjölk yogurt drink "culture" and stirred it. I poured 1 quart of that mixture into a mason jar, sealed it, and left it out at room temperature (around 75-77°F). The remaining 3 quarts were heated back to ~115°F. Both yogurts fermented for about 16 hours before going in the fridge.

Both yogurts seemed to have about the same thickness, but the mesophilic yogurt seemed smoother with less lumps. The big difference is in the taste. The thermophilic yogurt has a clear sour/tangy taste as usual, but the mesophilic yogurt is very mild by comparison. That seems to conflict with what this page says about filmjölk (that it has a mild tartness, which I didn't really detect), but it seems clear that the thermophilic strains put out a lot more lactic acid. Increasing the fermentation time would probably have had an effect as well. My taste tester preferred the thermophilic yogurt, but enjoyed both. You could see the sour yogurt as having more uses (such as replacing sour cream or buttermilk in recipes).

I think the next step here would be to try using random storebought yogurt to make mesophilic yogurt. The stuff I used had 10 strains in it, while most yogurts have just 2-3. However, the safe bet is to just make it using the thermophilic process, since almost all of them should have Lactobacillus bulgaricus or Streptococcus thermophilus.

How cheap can you find a gallon of milk? I've seen whole milk at $1-2, and that's basically how much the yogurt costs (maybe with half of a $0.25 cup of yogurt if you aren't back-slopping). The time spent is minimal when using the Instant Pot. Maybe 5-10 minutes in total to pour milk in, hit a button, set the pot aside so it can cool faster, check the temperature with an instant thermometer, stir starter in, hit another button, pour into jars/containers for the fridge, and rinse the pot out. It just takes a day for it all to go down.

Threadripper 2990X Price Leak

AMD Threadripper 2990X leak suggests it'll be much cheaper than Intel's i9-7980XE chip

AN OVERLY-KEEN German retailer has potentially revealed how much AMD's upcoming Threadripper 2990X will cost.

Videocardz spotted the since-removed listing at Cyperport, which listed the 32-core CPU with a €1,509 (around £1,300) price-tag, making it roughly €500 more expensive than AMD's 16-core Threadripper 1950X at launch.

However, it also makes the CPU almost €500 cheaper than Intel's Core i9-7980XE flagship, despite the fact that AMD's 32-core chip will likely offer close to double the performance of the lesser-spec, 18-core chip.

$1,500 USD?

Remember when Joe Biden got refused service...

...and the shop owner got invited to speak at GOP rallies?

Remembering when a baker turned away Joe Biden and received praise from conservatives

The Red Hen isn’t the first Virginia business to bake up controversy by rejecting a political figure’s business.

The owner of a cookie shop turned down the opportunity to serve Vice President Joe Biden in 2012 — and the right embraced him as their small business hero.

He made the decision “because of conviction and principle,” the shop owner told CBS affiliate WDBJ 7 at the time. “I have a difference of opinion of the folks in that campaign, that’s what it was. Also, taking a stance for my faith, my faith in God.”

McMurray’s story was thrust into the national spotlight with the help of conservative news sites, blogs and the wide-reaching Drudge Report. It eventually caught the eye of Paul Ryan, the Republican Party’s Vice Presidential nominee at the time, who requested that McMurray introduce him at rally in Roanoke a few weeks later.

Thermophilic vs. Mesophilic Yogurt Making

Normally when I want to make yogurt, I use a thermophilic process:

1. Heat/boil a gallon of milk to kill (reduce) whatever is in it.
2. Let it cool down to about 115-120°F (45-50°C).
3. Stir in a few tablespoons of store-bought yogurt, or "back-slopped" yogurt from the previous batch.
4. Hold it at 115°F/45°C for 8 - 16 hours.
5. Store in fridge.

You can use a yogurt maker, but some Instant Pots come with a yogurt function and if your oven can keep the temperature at 115°F/45°C, then you can just put a covered pot of it in there.

I got a couple of these on clearance with the intention of using one as a starter culture. It supposedly contains these active cultures:

L. lactis subsp. lactis, L. lactis subsp. cremoris, L. lactis subsp. lactis biovar diacetylactis, Leuconostoc subsp. cremoris, S. thermophilus, L. bulgaricus, L. rhamnosus, L. casei, L. acidophilus, Bifidobacterium sp.

My bottle is almost identical (some of the names are reformatted):

L. lactis subsp. lactis, L. lactis subsp. cremoris, L. lactis subsp. lactis biovar diacetylactis, Leuconostoc spp., S. thermophilus, L. delbrueckii subsp. bulgaricus, L. rhamnosus, L. paracasei, L. acidophilus, Bifidobacterium spp.

Filmjölk is described as a mesophilic yogurt - with the strains added to cold milk, not boiled, and fermented at room temperature, i.e. 70-78°F (21-26°C). However, some of the strains listed above, such as thermophilus and bulgaricus, are clearly found in thermophilic process yogurts.

So should I just make it the thermophilic way like usual, do it at room temperature, or try to do each version? Is there a middle ground (such as keeping it warm for 4 hours, and then letting it drop to room temperature)?

The Incredible Shrinking Woman

Welp...just got back from a doctor's appointment for some routine bloodwork. Good news is I'm down to 159 lb--this in all clothes less shoes and with a big meal in me. Bad news is, somehow, I've *shrunk* about 2 inches, and can no longer use the phrase "six-foot dyke in steel-toed work boots." I mean, "five-foot-ten dyke in steel-toed work boots" doesn't have quite the same punch to it, you know? But the measure doesn't lie: 178cm, 5'10" on the dot.

And no one can tell me WTF happened there. If my mother's any indication there's almost 20 years still to go to menopause, and I haven't lost any bone or muscle mass. A co-worker about my age says she lost an inch a couple of years ago and the doctor told her it was bad posture, but I don't slouch, so...who knows?

Odd. This bugs me more than it ought to to be honest.

Trump admin changed its story on separation 14 times...

First it was a deterrent. Then it wasn’t.

It was a new Justice Department policy. Then it wasn’t.

The Trump administration was simply following the law. Then it said separations weren’t required by law.

It could not be reversed by executive order. Then it was.

President Trump’s political gambit to force an immigration bill through Congress backfired Wednesday amid a series of wildly contradictory statements — which you can see for yourself in the video above — from a White House that has been without a communications director since Hope Hicks left in March.

The Trump administration changed its story on family separation no fewer than 14 times before ending the policy

Man.....if only someone had pointed that out, repeatedly, over the last few days only to have posters swear up and down that Trump was telling the truth. You all willing to admit you were wrong yet?

XXXTentacion: Controversy rages after rapper's shooting death

The killing of US rapper XXXTentacion has set social media ablaze: vicious arguments have broken out about how to memorialise such a problematic figure, as fans pore over conspiracy theories about the perpetrator and even question if the rapper was killed at all.

Florida police have confirmed the 20-year-old, born Jahseh Dwayne Onfroy, was shot dead on Monday.

Despite this, fans are probing videos purporting to show him after the shooting. Posts online point out potential discrepancies in his facial tattoos and question the lack of visible blood, bullets and shattered glass in the footage. Some suggest his death was faked as part of an elaborate prank for a future video release.

A video from several months ago of XXXTentacion denying his own death (after an apparent suicide prank on his own channel) has also re-circulated widely, leading to further confusion.

[...] He spent much of last two years in and out of jail or on house arrest.

At the time of his death he was awaiting trial for beating and falsely imprisoning his former partner, Geneva Ayala, having already pled no contest to charges of home invasion robbery and aggravated battery with a firearm in a separate case.

I made this unaccepted submission about him a few weeks ago:

United States (Un-Ironically) Commemorates World Refugee Day

On World Refugee Day, we join the United Nations High Commissioner for Refugees and our international partners in commemorating the strength, courage, and resilience of millions of refugees worldwide who have been forced to flee their homes due to persecution and conflict.

As global displacement has reached record levels, it is vital that new actors – including governments, international financial institutions, and the private sector – come to the table to assist in the global response to address it. The United States will continue to be a world leader in providing humanitarian assistance and working to forge political solutions to the underlying conflicts that drive displacement.

I mean, sure, we'll send your children to an internment camp for the crime of applying for asylum. But, other than that, the US is totally down to help!
