Sweet potatoes are frequently enjoyed in cooler months, but this innovative recipe redefines their role, making them a star of summer barbecue. By incorporating grilling into their preparation, these tubers acquire a delightful smoky essence that complements the fresh, seasonal flavors of corn and poblano peppers, creating a unique and appealing side dish.
To ensure the sweet potatoes are tender and thoroughly cooked before grilling, they are briefly simmered. This initial cooking step guarantees they become soft enough to absorb the smoky flavors from the grill without becoming tough or undercooked. Once tender, they are brushed with olive oil and seasoned, preparing them for the intense heat of the grill.
The salad's vibrant character is largely due to its tangy dressing. A harmonious blend of olive oil, fresh lime juice, salt, pepper, and a hint of cayenne pepper creates a zesty and slightly spicy profile. This dressing is whisked together and infused with thinly sliced scallions, adding a fresh, aromatic kick that beautifully balances the richness of the sweet potatoes.
Fresh corn on the cob is generously coated with butter and seasoned before being wrapped in aluminum foil for grilling, which helps it steam and tenderize while developing a sweet, charred flavor. Poblano peppers are grilled directly until their skins are completely charred, a process that intensifies their smoky and fruity notes. After grilling, the poblano is steamed to facilitate easy peeling, ensuring a smooth, flavorful addition to the salad.
Whether using a charcoal or gas grill, proper heating is crucial for achieving the desired char and tenderness. For charcoal, briquettes are lit and spread evenly, creating a hot, consistent heat. Gas grills require all burners to be turned high to preheat, then adjusted to maintain a primary high-heat zone, ensuring the vegetables cook perfectly while acquiring that desirable grilled aroma and texture.
Once the sweet potatoes, corn, and poblano pepper are grilled to perfection, they are allowed to cool slightly before preparation. The sweet potatoes are cubed, corn kernels are removed from the cob, and the charred skin, stem, and seeds are discarded from the poblano before it is finely diced. These ingredients are then combined in a large bowl, ready to be tossed with the zesty dressing.
The prepared dressing is generously poured over the grilled sweet potatoes, corn, and diced poblano, then thoroughly tossed to ensure every piece is coated. The salad is allowed to rest for about 10 minutes, giving the flavors time to meld and deepen. Before serving, a final taste test allows for adjustments, adding more salt, pepper, or lime juice as needed to achieve a perfectly balanced and flavorful summer salad.
To prepare this delightful grilled sweet potato and corn salad, several key kitchen and grilling tools are recommended. A whisk is essential for blending the dressing ingredients smoothly. A medium saucepan is needed for pre-simmering the sweet potato slices. A 13- by 18-inch rimmed baking sheet provides ample space for preparing and seasoning the vegetables. For grilling, either a charcoal or gas grill is necessary. If opting for charcoal, a chimney starter is highly recommended for efficiently lighting briquettes. Finally, a pair of sturdy tongs is indispensable for safely handling the hot vegetables on the grill.
This grilled sweet potato and corn salad is not only delicious freshly made but also stores well, making it a convenient option for meal prep or enjoying leftovers. Any remaining salad can be refrigerated in an airtight container for up to five days. This allows the flavors to continue developing, sometimes even enhancing the taste over time, providing a ready-to-eat, flavorful side dish for nearly a week.
