I am surrounded by sugarbeet fields, so it is pretty obvious that I steal some and make a developer!
I chopped them (more leaves than roots this time of year of course) and boiled them for some time, then let the soup cool down to 32°, took the leaves and stuff out, added vitamin c and washing soda and developed a super 8 test stripe!
The result? Great! Good contrasts!
The smell? Like horseradish / Meerrettich. Yum!
