This is the picture that sold me on them for storage:
I used to either use Ziplocs or deli containers, but the cubes are soooooo much easier!
2. Instant Pot broth: I haven't given up on this yet, although it's been a long road to travel down. Most of my early batches did not come out ANYWHERE near where I wanted them to be. I found a non-standard approach on Facebook recently & have been working on that. The process is to set to your Instant Pot on Soup for 4 hours & then leave it on warming mode overnight. This has a couple benefits:
1) It gives the broth a deeper color & MUCH better flavor
2) It does a natural pressure release, so it doesn't stink up your house
That's the framework, but I haven't reached the point where I have a finished procedure for it yet - still WIP! However, I am now convinced that a solid pho base (and other rich broths & stocks) can be achieved in the IP, it's just a matter of chipping away on more batches in order to get it totally figured out. 2020 is the year!!
