An update on my coffee machine journey: I am churning through coffee like crazy but I think I'm starting to get better at it.
I really struggled with foaming milk until I found the right video. The early ones as well as the instruction manual just said stick it in and it gets foamy. I wasn't able to get any foam until the milk started boiling!
But I found a better video that explained that you need to have the steam wand almost at the surface so it's pulling in air, and after a bit of practice I think I'm getting it now. I think some steam wands have a hole to pull in air where mine doesn't.
