Help with tarantino quote!

Hello,

I want to use one of Tarantino’s quotes in my research proposal for graduate school, so I am trying to figure out where it appeared or when Tarantino said it. Here it is:

“It’s like a Reese’s peanut butter cup. It’s got boobs and gore, two great tastes that taste great together.”

I know that he was talking about hostel, but I cannot find the source of this quote anywhere. Jenna Fisher attributed this quote to Tarantino on Bravo’s 30 Even Scarier Movie Moments back in 2006. On AlmostSideways.com, the quote is also attributed to Tarantino, but again no source. Thank you for your help!
