In recent months, I've started using vital wheat gluten in making bread. I'm a big fan, it really does a good job.
But I only use half a tablespoon in a white loaf, so a bag lasts for a while. The bag I have is still half full, and says Best Before May 2024.
What I'm asking is: what happens to it beyond the Best Before date? I notice it's not a Use By. Is it like flour, where you have to check for weevils if it starts getting old? Or is it like yeast, becoming less effective over time?
(Please, I'm only looking for an answer from people who have experience of this, I'm capable of doing a five second googling for myself but I'd prefer expert advice.)
