Ruhlman's blog entry was just one of a few on making butter I coincidently stumbled across all at the same time last week. It sounded tasty, but not worth the effort, until I saw
this comment and
link to proper instructions for homemade cultured butter. I was convinced it was worth a shot, if for nothing else but the
real buttermilk byproduct I could use to make some tasty biscuits.
I started with a quart of heavy whipping cream and a half pint of buttermilk to act as the culture. Although Holly's instructions called for sanitizing all the instruments prior to inoculation, I skipped it even though I've got both iodophor and StarSan readily available from my beer and wine making (don't use bleach unless you
really rinse it out well. On second thought, don't use it at all- it wouldn't take much to leave an off-flavor in your butter, and whatever wild bugs were able to digest milk would probably just add to the flavor :)) I just combined the cream and buttermilk in my stand mixer bowl and put it in a hot water bath to bring it to ~85F, covered, and came back 10 hours later, expecting to find something gelatinous, or at least more viscous- but it didn't appear to have changed at all. Maybe the cultured buttermilk is pasteurized
after the culturing?
Considering its been sitting at fairly warm temperatures all day, I decided to churn it anyway, rather than waiting any longer and risk spoilage. Even with the stand mixer, it took a good 10 minutes at low speed- likely due to the lack of an established culture. For the first 9.5 minutes, it looked like it was just going to turn into whipped cream. But while I was out of the kitchen no longer than 90 seconds, it suddenly "broke" and turned into butter and buttermilk. W00t!
At this point you're almost done. First
seperate the butter from the buttermilk, then rinse the butter with cold water until the water runs clear, add salt if you prefer, and remove any remaining water. I did this by using the
whisk to cut the butter then draining any fluids, although next time I'll probably just make sure its good and cold and work it with my hands. Thats it- very simple stuff if you've got a stand or hand mixer.
How does it taste? Good! Very full buttery flavor, a bit sweet. I added salt to help preserve things, and because I mostly plan on just slathering it on bread. The salt definitely enhanced the flavor. What would I do differently? I've already ordered the creme fraiche and buttermilk cultures from
cheesemaking.com for the next round. It would be great to find a local dairy farmer willing to sell cream by the gallon- anyone in the bay area with the moo juice hookup? Maybe I could mass produce it and take over the
Rama butter market in the US.
