Legend has it that coffee was discovered by Kaldi, an Ethiopian goatherd who noticed that his goats became more energetic after eating the berries of the bush and became inspired to chew some himself. Other tales—likely equally apocryphal—credit Sheikh Omar of Yemen, who supposedly tried boiling coffee beans while living in exile in the desert.
Whatever coffee's origin, it's so popular today that productivity in the U.S. would likely grind to a halt if it suddenly became unavailable. The main challenge in cooking with coffee, Ben Sheagren said, is bitterness. As chef at the Hopleaf, he cooks with beer quite a bit. But he thinks the bitterness found in coffee is different from that of beer.
"The hop is more automatically associated with a vegetative quality. It can be fruity, it can be grassy, it can be piney, soapy," he said. "Where the bitterness from coffee is more acidic, more sharp."
They also react differently to cooking. "Bitterness in beer tends to be accentuated," Sheagren said. With coffee, "you're going to have the same level of bitterness. It's a fairly predictable ingredient."
Not surprisingly, Sheagren ended up using beer as well as coffee—Red Eye coffee porter from Two Brothers. It seemed like a natural pairing to him. In fact, he thinks there's a beer appropriate for almost any dish, "whether it be the lightest, brightest vinaigrette-type application or the deepest, richest, darkest demiglace. There's a flavor profile that's going to work."
Sheagren brined some lamb racks in Metropolis coffee before doing a dry rub of ground coffee, salt, and sugar and hanging them up in the walk-in cooler for about a week. He then frenched them, leaving most of the fat cap on to protect the meat from the fire, and roasted them in a wood-burning grill with hickory.
The coffee porter went into a lamb jus, along with an espresso blend from Intelligentsia. "I was looking for as many ways as possible to incorporate coffee into the dish without steering it into the overwhelming area," he said. He even tried putting coffee in the smoker while smoking some cherries, but the burnt coffee aroma quickly made him change his mind.
The sides were the hardest part of the dish, Sheagren said; pairing coffee and fruit is relatively easy, but vegetables are another matter. He ended up making carrot puree, glazed fennel bulb, and braised pear.
Despite all the applications of coffee in the dish, the coffee flavor was relatively mild. "I'm pleasantly surprised that the bitterness of the coffee didn't transcend every other element on the plate," Sheagren said. "You get it a lot more from the aroma. You experience more of the scent than you do on the palate. The nose is a much more forgiving experiencer of flavor, so to speak, than the tongue."
Michael Shrader of Urban Union, working with curly parsley. "The ubiquitous curly parsley sprig as garnish is the worst nightmare of any serious chef," Sheagren said. "It's probably the most overused, abused, and taken-for-granted ingredient and garnish that has ever hit a plate. I figured, as pedestrian an ingredient as it is, the inherent challenge would be to elevate it beyond its humble and cliched roots."
