Flour is many years expired but still looks good
I am using flour that expired in 2018. I had to use some of my emergency flour due to the corona virus shortages. Its pretty good but not as good as fresh. Id say 90% as good tasting. Yeast on the other hand is different. Ive had a one pound block of yeast in the freezer since 2014 and it still works. Not very well but it works. I have to double up the amount and wait twice as long so the bread tastes very yeasty but it is good to know it can last this long.
