Sweet and salty are the two basic food groups of snacks. So of course someone would want to combine them.

Food company Mondelez International has taken two of its brands — Oreo cookies and Ritz crackers — and merged them into a new confection that’s either an act of genius or a crime against nature.

The treat replaces one of the cookies of an Oreo with a Ritz cracker, and unites them with a layer of peanut butter filling and a layer of traditional Oreo cream.

Mondelez is feeling so upbeat about the mix, it’s giving away free samples.

To score yours, go to this website after 9 a.m. Pacific on Thursday and put in a request, But move fast. Only 1,000 freebies will be available. (You can sign up in advance for an email alert.)

Oh, and “free” is relative. You’ll still have to pay $3.95 for shipping.
