BBQ Thermostat: Arduino MKR 1010 and Therm Shield measuring temperature during a smoke
Today I was smoking a turkey so I figured it was a good time to do a live test of my project. There was good news and bad news. I think it’s illustrated quite well by the following graph:
Grafana graph of my BBQ Thermostat while measuring the smoker temp
I recently started an electronics hacking project to build a thermostat for my Weber Smokey Mountain. You can find details at Hackaday.io, but if you’ve been here long enough you know that I don’t trust other sites to continue to exist. (It’s why I copy my book reviews over from Good Reads). As of right now I’ve got the board able to read temperatures from a thermocouple that I send, via WiFi, to an MQTT broker. Then, via Python I take subscribe to that MQTT topic and put it into InfluxDB. From there I use Grafana to graph it. Here’s an early beta where I was trying to make sure it was working from end-to-end:
Macadamia nut, White Chocolate, and Cranberry Cookies
In January I made a lot less new things than in previous months, but I did prove that even in sub-freezing temperatures I still BBQ and Smoke. My least favorite were the macadamia nut, white chocolate, and cranberry cookies. I’ve liked white chocolate and macadamia nut cookies in the past, but this was my first time adding cranberries. But it was the macadamia nuts I wasn’t a fan of this time. I’m not sure why, I just didn’t liek the taste. The fattoush was a neat taste for a new salad and I learned how easy it is to make your own pita chips! The glazed ribs were OK, but I didn’t fill the water pan in the Weber Smokey Mountain and I think that led to a more smokey/burnt taste as the glaze dripped off and into the empty water pan. The Big Butts Pork Steak was pretty awesome, though. The recipe also contained my favorite home-made BBQ sauce. I definitely look forward to revisiting that recipe!
Last time I was in Florida my mom took me to a specialty BBQ store, Just Grillin, off of Dale Mabry in Carrollwood. I didn’t know such places existed. I thought everyone just bought their grills at a hardware store, Amazon, or direct from the company. It was a pretty great to be able to see and touch Yoders, Weber Summits, and other high-end BBQs. They also came by with some chicken they’d cooked in the back using a variety of rubs they sell. Oh yeah, the entire wall behind the register was full to the brim with rubs and sauces - most (if not all) of them local or competition group rubs. Any rub you wanted to try would be poured into a tasting cup. Sure, it’s not the same as having the rub on some food, but it’s certainly better than the blind buying we have to do with supermarket rubs. As a gift, mom said she’d get me any rub I wanted to try, so I picked up Thunderbird Chicken Scratch. Then a bunch of travel meant I had to keep waiting impatiently until I could finally try it. Last night I finally got my chance.
Part of the fun of being into BBQ has been trying new things. As I’ve mentioned before, when I was growing up “BBQ” was what we called grilling and it MOSTLY consisted of burgers and hot dogs. Very occasionally it would be something else. Lots of lighter fluid and mediocre results. But now I know about low and slow and smoking and 2-zone grilling. And once I mastered ribs, chicken, and brisket it was time to experiment. So I tried Meathead’s recipe for Alabama Birds with White Sauce.
In the past few years I’ve been moving away from seeing pizza as junk food towards seeing it as another food that is sometimes made with care, skill, and love and sometimes make in a hurry for a buck. I can’t remember the exact timeline and can’t be bothered to search for photo evidence, but the two restaurants that changed my mind on pizza were Two Amys in Maryland and Grimaldi’s in Brooklyn. Two very different styles of pizza, but Grimaldi’s cooked in a fire-based pizza oven and authentic Neopolitan at Two Amys. So now there was a new measurement against which to measure all pizzas: the wood-fired pizza.
Do you know why a lot of people don’t BBQ that often? Because they always make the same thing and that’s boring. So I’ve been going through all the recipes in Meathead’s book (and other sources) to see if anything else is tasty to my palette. This time it was smoked chicken. I cut the chicken in half.
I took the skin off because Danielle was going to take off the skin anyway and since this was a rub-based recipe, that would remove all the flavor as well.
I’d tackled all the major BBQ meats. It was time to try and make my own sauce. So I assembled all my ingredients and followed Meathead’s recipe. It’s supposed to be like KC Classic, which I’ve never had. I also went with the secret optional ingredient of Tamarind paste.
Then I finished cooking
And canned it while it was still hot:
So what was the verdict? Again, I’ve never had KC Classic. My favorite commercial BBQ sauce is Trader Joe’s Kansas City sauce and that’s nice and sweat. This sauce was very tangy. While it has grown on me over the past couple months, it’s definitely not my favorite and my wife doesn’t like it at all. I want to try one more time, this time tweaking it to be a sweeter sauce. Also, I want to see how it changes when caramelized, something I haven’t had a chance to do yet. Still, it was fun to make my own and add it to my other BBQ/smoke creations.
I had been wanting to do brisket for a very long time, but I couldn’t find anywhere convenient to buy a whole packer brisket. But right before I was convinced I was going to have to go to a butcher, Costco decided to carry them.
Yeah, it was 20 lbs, which is ridiculous for what was essentially going to be just 3 adults, but it was USDA Prime for only $3/lb! I had no choice. I put it in my shopping cart and resolved to deal with the consequences later.
