very quick question for clever bakers

[Rowlers]

Can I use sour cream instead of buttermilk? I know I can mock up buttermilk using milk and lemon juice but have sour cream in fridge which would be quicker!

Yep, I would.
Might need slightly more other liquid - or add a little milk to the sour cream to thin it out slightly?

Definitely, as above - just thin it out with some milk until it's the same viscocity as buttermilk.

Fab great thanks
