It took maybe 10 minutes to turn into butter. I'm sure it's because I chanted Mama Pea's song! I poured out the milky stuff - maybe 3-1/2-ish cups.
I rinsed the butter a few times in the churn, and then put it into a bowl and added salt. Mama Pea said 1 tablespoon per pound - I added 1 tablespoon for all I had, almost 2 pounds, and that was plenty.
I wanted to taste the buttery goodness of it, so I made pancakes for dinner using the buttermilk as the liquid, and slathered the yellow stuff on top. Yum.
