For years, I avoided recipes that called for sumac or relied on poor facsimiles using lemon juice.
Every time I saw sumac in an ingredients list I would immediately begin to itch. I couldn't help but think of poison sumac and its itchy associates, poison ivy and poison oak.
But my qualms were needless. And so are my fears of poison sumac — it doesn't grow in Arkansas or Missouri, and its berries are white.
Today, sumac is one of my favorite spices. I use it almost as much as cumin and dried chiles. It adds a vibrant, tart, citrusy punch to whatever you sprinkle it on. Look for it at Middle Eastern grocers and some specialty stores.
There are about 35 varieties of sumac, all members of the Anacardiaceae family (cashews, mangoes and pistachios are also members of this family). The sumac found in spice jars is most often Rhus coriaria, or Sicilian sumac.
Culinary sumac, used widely in Middle Eastern and Mediterranean cuisine, is a shrub that produces dark red berries. These berries are harvested, dried and ground into flakes or powder.
If you've spent any time on Interstate 40 between Conway and Fort Smith, Arkansas, you've seen smooth sumac (Rhus glabra).
The shrubs grow in clusters and each fall put on a colorful show as their foliage turns from green to orange and red.
Its berries are sometimes used to make tea, according to the University of Arkansas Cooperative Extension Service.
Another edible sumac found in Arkansas is fragrant sumac (Rhus aromatica), which, according to the plant society looks remarkably similar to poison oak and ivy. Remember the old adage: Leaves of three, let it be — because poison oak and ivy, after all, also produce red berries.
In this sheet pan recipe, the spice is used to flavor chicken and butternut squash.
SUMAC CHICKEN WITH BUTTERNUT SQUASH, RED ONION AND TAHINI-YOGURT SAUCE
Makes: about 4 servings
2 pounds bone-in, skin-on chicken pieces
1 large red onion, halved and sliced
2 cloves garlic, smashed
2 teaspoons ground sumac, divided use
teaspoon red chile flakes such as Urfa biber or Aleppo, optional
4 tablespoons olive oil, divided use
1 teaspoons salt, divided use
teaspoon black pepper, divided use
1 lemon, zested and juiced
1 small butternut squash, peeled, seeded, and cut into chunks or wedges no thicker than 1 inch and no longer than 2 inches
cup Good on Everything Tahini-Yogurt Sauce (recipe follows)
cup packed fresh cilantro, parsley, or mint leaves, chopped
In a large bowl, combine the chicken, sliced onion, smashed garlic, 1 teaspoon of the sumac, the cumin, red pepper flakes, 2 tablespoons of the oil, 1 teaspoon of the salt, teaspoon of the black pepper, lemon zest and half of the lemon juice and toss. Cover with plastic (or transfer to an airtight plastic bag) and chill for at least 12 hours.
Heat oven to 450 degrees.
While the oven heats, remove the chicken from the fridge and let it come to room temperature.
Toss the butternut squash chunks with the remaining 2 tablespoons olive oil, teaspoon salt and teaspoon black pepper and spread onto a sheet pan in a single layer. Arrange the chicken, skin-side up, on a separate sheet pan and scatter the onions around and in between.
Bake both pans for 20 minutes and then transfer the squash to the pan with the chicken and continue roasting until chicken skin is golden brown and the meat reaches an internal temperature of 165 degrees, 20 to 40 minutes more — actual cooking time will vary depending on the thickness of the chicken pieces.
Drizzle the tahini-yogurt sauce over everything and sprinkle with the remaining 1 teaspoon sumac. Scatter the fresh herbs over the top and serve with the remaining lemon half on the side, for spritzing over the chicken as desired.
GOOD ON EVERYTHING TAHINI-YOGURT SAUCE
1 teaspoon lemon zest
1 tablespoon lemon juice
1 small clove garlic, finely grated
teaspoon salt, plus more if needed
Pinch of black pepper, or to taste
1 tablespoon olive oil, or more to taste
In a small bowl, combine the tahini, lemon zest, lemon juice, yogurt, garlic, salt and pepper. Taste for seasoning and add more salt or pepper. Whisk in a tablespoon of olive oil. If desired, thin it out with a little water or just more olive oil. The sauce can be kept, refrigerated, for up to one week.
