Newbie here though I've been reading this site and others for a while now. I have a question maybe someone could explain to me - I am looking at different size baskets for making espresso, and I would like to know why (or if) a larger basket can't be used for smaller doses? The upper limit on dose seems obvious (you can only fit so many eggs in one basket), but most baskets list a lower limit to dose size as well.
What negative effects would result in, for example, using a "22 gram" basket for a 10 gram dose besides just looking funny?
While writing this I realized maybe all of that open space would make it harder for the machine to create enough pressure for extraction... is this part of it? Seems like that wouldn't be so hard to overcome. Looking forward to hearing your responses!
