Very interesting articles, and it brought me to buy your books, thank you. I am interested to know the shelf-life after opening these products, and how best to store them: Xanthan gum, Carrageenan Iota, Powdered and liquid lecithin, Tapioca maltodextrin. Do you have the answers to this?
Hi Leif, that's a great question!
I know I've never had any issues with my modernist ingredients not working because of age, but I've only been cooking with them for a few years! I decided to reach out to my friends at Modernist Pantry and see what they had to say. Janie wrote back:
All of our ingredients have a best by date of at least 2 years from date of manufacture. But in reality many are good for well beyond that date. They are also shelf stable and can be stored in your pantry.
So you should be just fine if you store your modernist ingredients in a sealed container in the pantry for at least 2 years, not too shabby!
