Our question this time comes from Mark in Greenfield, who asks:

What's the secret to the Secret Stadium Sauce at Miller Park?

At first, our panel of experts wondered if this question was rhetorical. Most Milwaukeeans -- be they diehard baseball fans or folks who think that a hit and run is what happens in the shopping mall parking lot -- have sampled Secret Stadium Sauce at a baseball game or barbecue at some point.

But, we're here to help the uninitiated, as well.

Secret Stadium Sauce is a condiment developed by Sportservice, the vendor at Miller Park and its predecessor, County Stadium. It is served on bratwurst, hot dogs and other sausages and became so popular that it was packaged in 18-oz. bottles and sold at the Brewers FanZone store and in regional grocery stores.

The origin of the Secret Stadium Sauce is murky, which is why it's a secret.

Rick Abramson, who worked his way up from County Stadium vendor to the president of Delaware North Companies Sportservice, is credited with inventing the sauce during the 1970s.

Abramson recently told the Milwaukee Journal Sentinel that he and a group of co-workers wanted to "come up with something" and started mixing barbecue sauce, ketchup and mustard.

"It just sprung up and people walked up and started using it," Abramson told the newspaper. (NBC announcer) Bob Costas became a fan of it, and started talking about it. We began to bottle it, package it and sell it in grocery stores. It has been a cult treat since."

In an interview last fall, Tom Olson, the general manager of Sportservice operations at Miller Park, offered a slightly different version.

"Back in the '70s, when Rick Abramson was around, we ordered ketchup from our vendor," Olson said. "When they went to that palette to send some ketchup up to the concession stands, they discovered that it wasn't ketchup but barbecue sauce.

"There was nothing anyone could do. It was either that or nothing. Somebody said 'Put it on the grill and warm it up.' That's what they did. The next thing you know, Rick is asking, 'How about getting it bottled?'"

A legend was born.

Costas helped fuel the sauce's popularity by talking about the sauce during "Game of the Week" broadcasts and other appearances during the 1980s. He talked about the phenomenon in Curt Smith's book "Storied Stadiums: Baseball's History Through Its Ballparks."

"The secret sauce has a formula that's in a vault that makes it taste like another planet," Costas told Smith. "Put beer on the grill and steep it in sauerkraut. On camera, I'd say it's now an official game because have the bratwurst.

"We'd (Costas and partner Tony Kubek) have to alternate play-by-play because one of us would have a mouthful. This became semi-legendary, especially in Wisconsin, to where the concessionaire at County Stadium sent vats of bratwurst to my home in giant industrial size. I'd get jars of the secret sauce, but also letters form Cub fans who where insulted that I didn't say Wrigley Field had better hot dogs."

The story took on another dimension when Costas told a tale of his communication with Ma Pesh, a brat lover from Stevens Point.

"Ma wants to challenge me to a bratwurst eating contest," Costas said in Smith's book. "He enclosed a Polaroid and the guy had to tip the Toledos at about 430. Ma wears bib overalls, he's got a big head, looks like Junior Samples and claims he holds the record for County bratwurst consumption. Says he consumed the most brats in a game between the Brewers and Orioles in August 1972 -- and that this was even more surprising because before then he'd never eaten well against Baltimore. You know, what do ya' say? I wrote back and he wrote back to me and now we're pen pals."

Thousands of bottles of sauce later, the legend lives on.
