Random #Thanksgiving #Food notes
if you pressure cook an unopened can of pumpkin puree (and then let it cool slow) before opening - you will get a richer deeper flavored caramelized pumpkin puree for pie or other use

Tonight I took a recipe my mom had for date oat bars and made a whole bunch of substitutions and tweaks to make a cranberry oat crumble that is dairy-free and gluten-free. It's delicious 😋

I have a lot of fun doing this sort of recipe tinkering. I keep a kitchen lab notebook for the recipes I create or modify. My spouse suggested that I show it to my chemistry students. I use a lot of the same habits

@Take_A_Bow @xvf17 oh awesome!
Reminds me of something similar (on a webpage) I used to show kids in my #KitchenChemistry class. ( oh that nearly 15 yrs ago).
Thanks for the link!!

I'm incredibly blessed with so many great memories 👆🏽 of my late friend Bob Wolke (and we did meet late in our lives, much earlier in mine tho).
I knew of him before I moved to Pittsburgh - didn't realize he was here until just before I was introduced to him by a colleague.

You too can gain much, as I did, from his wisdom and expertise through his books on #Food + #Science
It's what led me (before we met) to use #KitchenChemistry to teach #Chemistry through food

Last one in what ended up as a short thread on umami response
Proteins breakdown and many of the amino acids, not just glutamate, produce an umami response.

There's glutamate in mother's milk, and enhanced umami (glutamate) in say vegetable soup produces a more favorable response from babies

In case you know of umami but don't know about differences in response to glutamate (there's a lot in kombu) and inosinate (there's a lot in katsuoboshi) and guanylate (there's a lot in shiitake, especially dried) - know that there is a synergy between these.
Hence my mixing of the 3 for the dashi 👆🏽<technically 2 would have been ok>

Here's a good review article

Umami the Fifth Basic Taste: History of Studies on Receptor Mechanisms and Role as a Food Flavor - PubMed

Three umami substances (glutamate, 5'-inosinate, and 5'-guanylate) were found by Japanese scientists, but umami has not been recognized in Europe and America for a long time. In the late 1900s, umami was internationally recognized as the fifth basic taste based on psychophysical, electrophysiologica …

Details are everything.
The sole difference when making Indian Paneer versus Mexican Queso Fresco is 30°F in when you add the acid to the milk.
The chemistry at the two different temperature is so profoundly different that they both have different cooking and melting properties once completed.
Paneer is harder and resists melting and the Queso Fresco is soft and melts (think quesadillas).
