How to care for Boo's boards?

I use Boo's Block Board Cream. Williams Sonoma, among many others, carry it.

I currently use mineral oil on my cutting boards, but when I polish off my bottle, I'm going to try Heidi Swanson's Spoon Butter recipe: http://www.101cookbooks.com/archives/spoon-butter-recipe.html.
