Speaking of storing things in the freezer, I should learn to cook extra farro and store it there too. For the burgers, you need to cook farro and peeled red potatoes separately, and then let them cool before adding the other ingredients. The mushrooms were finely chopped and cooked in butter with rosemary and thyme before being transferred to a large mixing bowl with the farro and potatoes. Then, finely chopped shallots were sauteed, and the pan was deglazed with white wine. The shallots were added to the mushroom mixture with Parmigiano-Reggiano cheese. The mixture was mashed together with a potato masher, and burgers were formed. Each burger was pressed into a plate of panko breadcrumbs on both sides and set aside. While these steps were happening, I was also simmering the chutney. The chutney was started by cooking curry leaves, dried chiles, mustard seeds, and cumin seeds in canola oil. Turmeric was added followed by onion and then peanuts. After a few minutes, chopped, fresh tomatoes, and I used cherry tomatoes, tomato paste, sugar, curry powder, cayenne, and salt were added. The chutney simmered for about 40 minutes until thick. The burgers were browned in olive oil over medium heat until golden and warmed through.
These aren’t the kind of burgers you can throw on the grill, but they’re fantastic burgers just the same. They’re not sturdy enough to sit on or be flipped on the grill grate, and grilling wouldn’t result in the same crispy, browned surface you can only get from cooking in oil. They had great, savory flavor from the mushrooms, shallots, parmesan, and herbs. You could serve them on buns, but I chose to pair them with salad for a delightfully different take on burgers and ketchup.
