It's fair to say that our friends at Yorkshire Tea take their dunking seriously. So seriously that they've undertaken a proper science experiment to find out which biscuits dunk and which ones don't.
(I mean who wants a biscuit that's going to disintegrate the second it hits your tea??)
See how they got on with each biscuit by watching the videos below.
So there you have it. Scientific proof of which biscuit is the best to dunk. Let us know which biscuits you most like to have with your tea and join the conversation on social media using the hashtag #YorkshireTogether.
