and realized maybe I should get a larger one to have more time?
Nobody else has asked this, and you didn't say -
Are you putting the pitcher in the freezer? That will give you more time.
Are you using skim, 2% or half and half?
I know that skim and 2% are easier - for me, anyhow.
I don't have an Mcal, I have a Cremina, so I can only post in general terms.
I'm guessing you don't have the hang of it yet.
So, go back to basics.
Freeze the pitcher, try it with 2% or skim.
Fill pitcher slightly over half full.
ETA - don't forget to blow the condensate out of the steam arm prior to steaming.
Start out stretching - noise - tthwip, thwip, thwip -
Stretch until plenty of volume or warm to hand on side.
then Put tip deeper down along side, ( bout halfway down) watch for swirling motion to get microfoam.
then when side of pitcher gets hot to hand, stop.
We deal with smaller volumes than most cafes do. So, your technique will be different.
I'm thinking you may be getting it too hot - causing it to reliquify.
I'm guessing from the info that you are posting that you are going way to long - heating it too hot, which kills the foam.
If the steam is "blasting the crap out the milk"
Turn steam down, realize you must work quicker
Try 2% or lower fat - try the 12 oz pitcher
ETAA - I posted and saw Bill's post - my wife's skim is a lot easier to foam than my half and half, for me anyhow.
ETAA - ultrapastuerized milk seems to work best
