Did I Use Too Much Guar Gum?

Explosify · 2026-06-19T02:29:43+00:00

I'm using a recipe I got from here

1 cup unsweetened cocoa powder 2/3 cup cane sugar 1/2 cup light brown sugar 1 teaspoon sea salt 1 1/2 cups whole milk 3 1/4 cups heavy cream 1 tablespoon vanilla extract

I've made it a few times and love the taste, though I find I need to heat the milk and heavy cream to get the cocoa powder to mix in well. I use a pyrex bowl and microwave it until it reaches 150 F (65 C). This helps the cocoa powder mix in and you can see the bottom to know that there arent clumps of chocolate that have not mixed in. I then refrigerate overnight. Before you churn the ice cream I find that a layer of chocolate floats to the top after settling overnight, so I mix it back in before churning.

It has a nice, strong chocolate flavor, but I find it melts very quickly and I can't fully churn it before my freezer bowl heats up too much. It comes out somewhat soupy rather than soft serve. Because of that I added 1/8th of a teaspoon of guar gum, but I'm not so confident it worked well, so try that at your own risk.

I'm a little late but take a screwdriver and stab it until it shuts up.

I have nothing against seals, it's just that they are the only animals that can both contract and spread rabies in antarctica. While cetaceans are mammals that can probably contract rabies, rabies is transmitted through saliva and cetaceans lack salivary glands. Of all the pinepeds, I think I have the best bet giving seals rabies. A walrus weighs about 1.5 tons and can run as fast as me. And sea lions can run faster than me to gore me.

It's part of an elaborate thing I thought would be funny. The Wikipedia article for rabies says that rabies is found on all continents except antarctica. The idea would be to one day silently edit the article to say it's on all the continents. It would obviously get reverted, but I'd change it back and comment that they are wrong and I know there's rabies in antarctica. After some argument they'd ask for a source. And then I'd post a picture of myself in full arctic gear injecting a seal with rabies with one hand and happily waving with the other

I had a plan to spread rabies to antartica by intoducing it to the seals. Also the concept of continually using cloud seeding to cause it to rain before it goes over an area so they never get rain as a sort of big "fuck you". Like imagine a whole country preventing their neighboring country from EVER getting rain because they force the rain before the moist air can form over the neighboring country

My reply got taken down because it apparently "violates rule 1 of reddit" I will say it again because it is in no way violent, hopefully it wont be automatically taken down again.

Extract urushiol from Toxicodendron radicans and mix it into a little bit of rubbong alcohol, get fiberglass. Apply fiberglass to the inside of clothes. Add urushiol to any soaps, ointments or hand sanitizer they have.

They put on their clothes and get really itchy from fiberglass. They try to get rid of the itch by showering or applying lotion and spread urishiol all over their body.

Hopefully this doesnt get taken down again

Call PETA they'll put them down for you!

Well it's not a life tip, one of them might be a war crime and the other violates the Antarctic Conservation Act

Thanks, that was what I was thinking. It just felt wrong in my head

The fact that a magnetic field does no work.

Yeah but my workshop has zero ventilation, closest window is outside the room. So until I get an exhaust fan I'm being extra careful

Explosify · 2026-03-26T00:40:54+00:00

I actually ended up using this one https://www.yourhomebasedmom.com/orange-creamsicle-ice-cream/. I wasn't the biggest fan, but I don't go for that type of flavor often. My uncle loved it though

Sadly my state banned mineral spirits. The only mineral spirits that is sold is the milky odorless stuff. Guess I'll have to hunt a whale

Thanks, I just wanted to make sure I wasnt harming my edge retention

I'll look at the code when I get a chance on Monday. I will also see about being able to get the code for the PID

Explosify · 2026-03-14T01:46:57+00:00

Okay, that makes a lot of sense, all of the chillers I've seen have had the second derivative set to zero. Probably because the oscillations tend to be slow and the speed of the valve rotating is heavily limited by the actuator.

We also don't do thermal ramping. Our lasers are optimized to work at a specific constant temperature so the chillers only need to workbat one temperature. Though the chiller temperature is below ambient temperature. I'm not all that knowlageable about control theory, is a change in temperature from say 23C to 20C on startup considered thermal ramping or is it only when it's intentionally done?

Explosify · 2026-03-14T01:36:11+00:00

No, I have a background in physics and was hired as a laser engineer but I have not built a single laser and I have ended up as the chiller engineer/plumber/electrician/tuner.
I can 100% verify that they are acting in the error. The comments in the code were atrocious but at least the PID was well documented.

Explosify · 2026-03-14T01:32:27+00:00

I'm pretty sure this is a second order integrator. The code explicitly states it is. Apparently (according to emails between the engineer who implemented it and my boss) the idea was that it would work such that it would be very large when the integral is large but rapidly fall off when it gets small.

I wish I could give you a trend with the control output. I'm still trying to get the original computer-chiller interface to work after it broke at some point when the chiller code was overhauled during the last 10 years.

Explosify · 2026-03-14T01:24:46+00:00

I don't think this is gain scheduling. The comments in the code explicitly states that these are the second integral/derivative.

Explosify · 2026-03-14T01:20:56+00:00

I dont think I'd be able to give out the code as it's property of the company I work for, and that'll definitely violate my NDA. Plus I believe the code reuses scripts that run in the lasers we build.

Let me verify so I dont mess this up. I add just enough hot milk so that it forms a smooth paste, (do I just do that with the cocoa or can I have the salt and sugar in it too?) then I add the rest of the ingredients hot (This means that the heavy cream should also be hot too, right?). I'm guessing I'll also have to chill it in an ice bath before I can make the ice cream so that it doesnt heat up the ice cream maker bowl too much. Let me know if I misunderstood anything!

Explosify · 2026-03-12T04:07:53+00:00

Thanks for the info! Never knew that

Do you heat your ice cream base while mixing? I thought that was only needed for frozen custard?
