The long-closed concession stand at Spring Lake will get a new snack shack on Saturday from Chef Bob Simontacchi’s Sonoma Burger.
Both Willi’s Wine Bar in Santa Rosa and Wurst in Healdsburg have them on their menus. With three eateries within a mile of one another offering smash burgers on their menus, Sebastopol appears to be the smash burger capital of the world. There are restaurants that specialize in the smash, such as Sonoma Burger, Blue Ridge Kitchen, and Fernbar in The Barlow.
Bob Simontacchi, the chef and co-owner of Sonoma Burger along with Brandon Parkhurst, the general manager, said: “I want to cook a burger I enjoy, and this is what happened.
Like so many other restaurant owners, they were forced by the pandemic to branch out from fine dining, which they still provide at Gravenstein Grill, the sister establishment of Sonoma Burger. The two tested a few pop-ups during the shutdown, according to Parkhurst. One sold pizzas and was called Pleasant Hill Pies. The other one eventually led to the creation of Sonoma Burger.
Whatβs a Smash burger?

Smash burgers have become increasingly popular, thanks in part to the rise of a Denver-based restaurant chain called Smashburger, founded in 2007. But the concept of smash burgers goes back much further.
Some attribute the dish to Dairy Cheer, a Kentucky fast-food restaurant that produced the burgers in the 1960s. While additional internet research indicates the 1934-founded Steak ‘n Shake chain as the true innovator, other sources claim it is a Great Lakes tradition.
The concept is fairly straightforward: beef patties that have been thinly sliced so that as much of the meat as possible contacts a sizzling hot grill.
Smash burgers are not without their critics. This kind of burger falls short for those who prefer a large, meaty patty. But Simontacchi prefers smash style just fine.
“I prefer to have the option of ordering a smaller burger, a shake, and fries”. πππ
Making a better burger

“We named it Sonoma Burger because we were able to source everything for the restaurant from Sonoma County,” explained Simontacchi, who became interested in food while stationed in Europe with the United States Air Force.
After serving in Operation Desert Storm, he used the GI Bill to attend culinary school at City College in San Francisco.
That training is what sets Sonoma Burger apart from other burger joints. Sauces and pickles are made from scratch. Then there are the golden, toasty buns with their enticing sheen.
“A great burger starts with a great bun,” Parkhurst said of the Parker House-style buns, which are baked fresh in-house every day.
Putting everything together

Cooking the burgers may be the first thing that comes to mind, but according to Simontacchi and Parkhurst, it is the last thing to do.
“Prepare your ingredients by slicing them and having them ready to go. “Separate your cheese,” Simontacchi said. “I prepare everything in front of me and then cook.” When you’re ready to cook, everything comes together quickly.”
They recommend toasting the buns first so you may devote your whole focus to the burgers. πππ
Simontacchi tried precut buns and found that they didn’t toast as well. If you don’t want to make your own buns, seek ones that you have to cut open yourself since they’re fresher.
To add another layer of texture to the burger, he butters the sliced buns and sets them cut side down on the frying surface until they’re bubbling and crisp. He softly flattens them with a fork as they cook, but a lightweight baking sheet would suffice.
When the buns are done, Spread sauce on both slices. Then it’s time for the main course.

Simontacchi uses a ball of flesh weighing 212 to 3 ounces, or the patty would be too large when squeezed out, he says. He seasons the ball well with salt and pepper, melts some butter in a skillet or grill, places the ball on the grill, and smashes.
