Display the latest post from a category

Hello,

I have been reading through the docs on this site and I am getting confused on how I should go about doing the following.

I want to be able to have on my sidebar the title / heading of the latest post from a particular category.
In this instance it would be the ‘Podcast’ category so when showing the title of the last post it would be showing the most recent episode of my podcast.

I hope this makes sense and I appreciate all help.

Regards
