Add some Wordpress post excerpts to homepage of custom theme

Hi :) I have a website here: [login to view URL]~jocelynp/. It uses a theme called Vernissage. You can see in the top-right, under the menu, where I've left a space called 'Where is Jocelyn?'. Here I'd like to display the 4 most recent blog entries in a specific category. No styling required. Thank you!
