Prepping Grain Spawn

Posted on July 19, 2024July 26, 2024

My last batch of grain spawn was in pints that I’ll be dividing in half for my baby buckets. As those are almost ready to go into buckets, I want to prep a new batch of true half pints to run my recipe with. Last time I was a bit short of grains using a 1 dry grain to get 3 wet ratio, so this time I’ll be trying 1 : 2*. My plans:

  • Soaking the grains overnight
  • Rinse, then cook for 15-20 min until al dente
  • Drain and letting steam dry it out
  • Loading into jars and pressure cooking for 90 minutes

I use rye berries from Azure Standard for my grain spawn.

*(Edit: 2024-07-21: with 1:2, I did 6 cups to yield 12 and instead got 20. 20/6 is back to the 1 dry to 3.3 wet ratio. Next time, for 12 wet: 12/3.3 = 3.6 cups dry)

Pressure Cooker Level Up

Posted on July 17, 2024July 18, 2024

Using a pressure cooker was outright scary for me the first time, but with the help of some friends and the reference to this awesome video, I got over my jitters. However, a year on, and it seems I’ve slipped up. I was watching a video on cordyceps and noticed he said he did not put the pressure regulator (cap that wiggles) on right away. He waited until a full steam got going, then did so. I went back to video for a refresher course and sure enough, do not put the regulator on right away. I also made note of the altitude comments he made, confirming that I should be reaching a pressure of 11 at my altitude.

Pressure Cooker vs Induction Stove

Posted on August 9, 2023July 18, 2024

Learned almost too late you SHOULD NOT put a pressure cooker on an induction stove (glass top stove).  It can cause it to crack!  So, my solution was a hot plate.  My pressure cooker is 16 qt, so a bit smaller than the 23 qt most people get for canning.  It managed to get up to pressure, but just not ideal.
