People who love ranch usually love ranch. I’ve seen folks dip pizza in ranch, dunk wings and chicken tenders and use ranch dressing on salads. Now you can dip a Whopper, too: Burger King and Hidden Valley have collab’ed on a ranch cup called “The Big Dip.” This XL cup holds a whopping 8 ounces of zesty ranch, more than enough to dip your entire Whopper.

Compared to Burger King’s usual 1-ounce dip cup, this is a major upgrade. Whether you’re looking to sauce up your burger, fries or nuggets with a side of ranch, you’ll have plenty of room to double-dip.

Everything We Know About the Burger King x Hidden Valley Big Dip Cup

I was ready to head to the nearest BK after hearing the breaking news, but I’ll have to wait to get both hands on this super-sized dipper. It drops on October 16th at 11 a.m. It’s the same Hidden Valley ranch dipping sauce that’s in the regular dip cup, but with a lot more to love.

“Once we introduced Hidden Valley Ranch to Burger King restaurants nationwide, we knew we wanted to celebrate the partnership in a big way,” said Pat O’Toole, chief marketing officer of Burger King. “We know our Guests love dipping everything in ranch—even their sandwiches—so we’re excited to deliver a Hidden Valley Ranch dip cup big enough for all of their dipping and dunking needs.”

Where can I find The Big Dip?

Head to New York, Los Angeles, Chicago, Miami, Dallas, Houston or San Francisco. Those lucky cities were chosen to debut the bigger, better cups at select BK locations. To see if your local Burger King has the goods, use this tracker before swinging by.

Limited quantities will be available while supplies last, but you’ll need to order a BK sandwich in person and ask for “The Big Dip” cup alongside. Sadly, the 8-ounce sauce is not available for delivery orders, and it can’t be combined with any other offers. You’ll also have to ask for this special sauce after 11 a.m., once Burger King’s breakfast hours conclude. Though we could get behind dipping a Chick’N Crisp Croissan’wich into ranch dressing, Burger King seems to think The Big Dip is more of a lunch and dinner condiment.

It’s also unclear how long this mega dip will be available, so act fast. Thankfully, the regular-sized ranch isn’t going anywhere.

How much is The Big Dip?

In more great news: It’s free! With the purchase of any BK sandwich, including Whoppers, Royal Crispy Chicken sandwiches, and yes, the Fish’N Crisp sandwich. Just ask for it inside one of the participating restaurants and they’ll hand it over for no additional cost.

If you don’t live near one of these ranch-loving cities, order one of the Big Dip cups for $1 on hiddenvalley.com starting at 11:00 a.m. on Wednesday, October 16.
