@ReWILDSaatgut unwalled article about Beetblue: https://m.phys.org/news/2020-04-blue-dye-red-beets-chemists.html
@ReWILDSaatgut and the research paper, also unwalled: https://advances.sciencemag.org/content/6/14/eaaz0421
Their procedure uses some nasty chemicals though... I wonder if we can modify it for the household kitchen 🤔
@ReWILDSaatgut ahh, probs not now that I look into the reagents/steps 🤷♀️
