Making buttered tea.
I've been wanting to try making buttered tea, and thinking about the churn, when today my eyes came to rest on my French Press, and the penny dropped into the slot.
I don't know if it's the right way to do it, but I brewed some tea, added some butter to the French Press, put the tea in on top of it, and successfully churned it into an emulsion. The result was quite tasty.
I don't know that I did it "right", but it's a start anyway.
