I believe my butter has turned rancid. It has passed the expiration date and tastes slightly sour. I read online that when butter turns rancid, the fats decompose and yield the fatty acid butyric acid, giving butter the sour taste. A website suggested to soak the rancid butter in a solution of baking soda to neutralize the butyric acid, thereby restoring the butter. Would the butter be safe to eat then?

I personally think it isn't because it was being cooled in the ice water, causing the equilibrium to shift to the products (because it is releasing heat)
