I’m calling bs. Post the lab results. Tested a bunch of ovens and everything consumer grade is garbage at keeping stabilized temp. I have done it in the oven a ton and have had decent results. Posting 99% conversion and having test results- let’s see em
Temp doesnt need to be 100% stable, it just needs to stay in a suitable range for an adequate length of time.
Here was the last test result for a concentrated MCT solution I made. The goal was 300 mg/ml and I got pretty damn close. When you bake extract in clear glass and can see when the bubbling stops, it's not hard to do. It is important to monitor temp though to make sure it's on point. My old oven I had to set it to 280F to achieve 250 but my new one holds temp accurately. All these devices work and are cool, but not necessary if you know what you're trying to achieve and how to get there.
