I'm curious if you are getting a full decarb at that 210° temperature for only two hours. I would think that you would need to go 8+ hours at that temperature to get a full decarb but then again, I'm no scientist.
I have done batches in my magical butter machine at 220° for two and four hours and have never felt like it was as potent as lately when I've been heating the flower up to 240° before adding to the oil. I do feel like the flavor changes a little bit when heated that high tho and I'd like to maintain more of the fresh flower taste. I'm trying to figure out what the lowest temperature/time would be to get a proper decarb but also maintain that fresh flower taste.
I am going to try my instant pot as well. Here is what I found on temperatures and pressure.
"The default setting of the pressure cooker is “high” (with a pressure of 10.2-11.6 psi and a temperature of 239°F-244°F), but you can adjust it to a lower pressure and temperature (5.8-7.2 psi and 229-233°F)"
I am thinking 1 Hour on manual High Heat/Pressure setting @ 239F-244F
I would go with the low temp/pressure setting for longer but Its hard to figure out the best time based on the graphs provided because the temp is between the 225F and 250F temp points that have been graphed with sample data.
other Benefits of instant pot are:
No smell versus oven decarb (pressure cooker is completely sealed- obviously)
more accurate temp versus oven
Full saturation of material and butter/water because of pressure
After the decarb step I will simmer it at 210F for an additional 8 hours in same pot so don't need to move or transfer anything.
