This is Sonora. Specifically the Sunday carne asada in a backyard parrilla in Hermosillo or Ciudad Obregon, where the mesquite has been burning since the morning and the cebollitas go on the grate beside the arrachera. You do not eat carne asada in Sonora without cebollitas asadas. The two are one dish in two parts.

The onion is the cebolla cambray, a Mexican spring onion with a small white bulb and long green tops. Pearl onions are not the same. Green scallions are not the same. If your supermarket does not carry cebolla cambray, find a Mexican mercado and ask for them by name. The bulb has to be big enough to soften on the inside while the outside blackens. The tops have to be long enough to wilt and char without disappearing.

The wood is mesquite. This is the chaparral country of northwestern Mexico, the wood is what grows here, and the flavor of mesquite smoke is in everything Sonora grills. Charcoal will work. Gas will get you a hot grate but not the smell. Cook this on whatever you have, but understand what you are missing if you do not have mesquite.

The finish is lime and a little salsa de soya. Yes, soy sauce. The norteno parrilla has used Maggi and soy on grilled meats and cebollitas for two generations. It is not a fusion gimmick. It is how it is eaten on the ranch and at the carne asada stands of Sonora. Crush a little chiltepin over the top if you want heat. Chiltepin is the wild northern chile, tiny, dried, ferocious. The chile of the sierra. Saber cocinar es saber vivir, and in Sonora that means knowing how to manage a mesquite fire.

The cebolla cambray takes its name from Cambrai, France, where similar small bulbing onions were cultivated in the medieval period and from which the variety traveled through Spain into colonial Mexico. The Sonoran tradition of grilling cebollitas alongside beef on a mesquite parrilla is rooted in the cattle ranching culture that has defined the state since the 17th century, when Jesuit missions and later Spanish ranchos established the open-fire grilling style that became carne asada. The presence of soy sauce on the Sonoran grilling table dates to the early 20th century and reflects both the Chinese-Mexican community of the borderlands and the broader northern habit of seasoning grilled meats with the bottled umami sauces, Maggi and salsa de soya, found on every parrillada table from Mexicali to Monterrey.

Equipment Needed

  • Long-handled tongs
  • Heavy sheet pan for prep and serving
  • Small jar for crushed chiltepin

Instructions

  1. 1

    Build a mesquite fire

    Light a generous bed of mesquite charcoal or mesquite wood in your parrilla and let it burn down until the coals glow red under a thin coat of gray ash. Mesquite is the wood of Sonora. It burns hot and dry and it gives off a perfume that is the smell of a northern weekend. Gas grills will get you close but they will not give you this. If you have no mesquite, lump charcoal will do. Briquettes will not.

    Build the fire to one side of the parrilla. You want a hot zone for the bulbs and a cooler zone where you can move the green tops once they start to blacken. This is the same fire that will cook your carne asada, so manage it like you mean it.
  2. 2

    Trim and prepare the cebollitas

    Trim the roots flush so the bulbs sit clean. Leave the green tops long, eight to ten inches, because they char and shrink. Peel off any papery outer layer that wants to come away. Rinse and dry the cebollitas completely. Water on the onions means a steamy onion instead of a charred one, and steamed cebollita is not what we are making.

  3. 3

    Dress and salt

    Lay the cebollitas flat on a sheet pan. Drizzle the oil or melted manteca de cerdo over them and roll each one until it is lightly coated, bulb and top. Sprinkle the kosher salt across them generously. Salt before they hit the grill. Salt after and it sits on the surface; salt before and it draws out the moisture and helps the bulb caramelize.

  4. 4

    Grill the bulbs first

    Lay the cebollitas directly on the grate over the hot zone, bulbs first into the heat with the green tops angled toward the cooler side. Let the bulbs sit untouched for about three minutes until the underside is deeply blackened in patches. Turn them with tongs to char the other side. The bulbs need real color, not a polite tan. You are looking for blistered, dark, almost burnt skin on the outside while the inside softens and turns sweet.

    If a green top catches fire, slide it to the cooler side of the parrilla for a moment. Some char on the tops is good. A full torch is not.
  5. 5

    Finish the tops

    Once the bulbs are blackened and yielding to a gentle squeeze with the tongs, lay the cebollitas flat across the grate so the green tops get their color too. Two minutes a side. The tops should wilt, blister, and turn deep brown in spots. The whole cebollita, bulb to tip, should look like it survived a small fire. That is exactly right. Total time on the parrilla is eight to twelve minutes depending on the size of the bulb.

  6. 6

    Dress at the parrilla and serve

    Pull the cebollitas off and pile them straight onto a platter. While they are still hot from the fire, squeeze the lime halves over the pile. The juice hits the charred skin and lifts the smoke. Sprinkle a little more salt. Set the soy sauce out alongside, in a small dish for dipping, and the crushed chiltepin in a tiny jar for anyone who wants the bite. Eat them with the fingers, wrapped in a warm flour tortilla with a piece of carne asada, or alone, straight off the platter. Asi se hace y punto.

Chef Tips

  • Buy cebolla cambray by the bunch from a Mexican grocer. The bulbs should be firm, white, about the size of a golf ball or a small egg. Skinny scallions are not the right onion and they will burn before the bulb has time to soften.
  • Mesquite is the wood. If you cannot find mesquite charcoal, lump hardwood charcoal will get you closer than briquettes. Throw a few mesquite chips on the coals if that is all you can find. The smoke is part of the recipe.
  • Do not skip the salsa de soya at the table. It sounds wrong to people who think Mexican food stops at lime and salt, but the norteno parrilla has used soy and Maggi for decades and the salt-umami hit on a charred cebollita is exactly right. No me vengas con atajos and do not come to me with purity arguments either.

Advance Preparation

  • The cebollitas can be trimmed, oiled, and salted up to two hours before they hit the grill. Hold them at room temperature on a sheet pan. Refrigerating them dulls the bulbs and they will not char as cleanly.
  • Cebollitas asadas are a parrilla dish. They do not reheat well. Make them when the fire is going and eat them while they are still hot from the grate.
