Preheat a grill to medium-high heat. Brush the corn with olive oil and grill for 2 minutes per side, or until char marks form. Remove from grill and set aside.: The air will smell warm and slightly metallic as the grill comes up to temperature, signaling it is ready to sear the corn . A medium-high heat gives you those attractive char marks while preserving juicy kernels. If you rush and use too hot a fire, the husks or surface will burn before the kernels cook through, so aim for steady heat. Common mistake to avoid is using a cold grill which results in pale, chewy corn rather than the popping, slightly crisp texture you want.
In a large bowl, combine the mayo, garlic, and lime zest and juice. Slice the kernels off the corn and add to the bowl along with the scallions. Stir to coat, then add the cheese, cilantro, smoked paprika, jalapeño, and salt. Season to taste and serve immediately or chill until ready to serve.: As the corn hits the hot grate you will hear a soft sizzle and the smell of caramelizing sugars will begin to rise, a cue that browning is happening. The extra-virgin olive oil helps the surface brown evenly and prevents sticking. Watch closely and rotate to develop even charring, because uneven cooking can leave raw pockets. A frequent error is leaving the corn unattended, which can cause flare ups and blackened areas that taste bitter.
Remove from grill and set aside: Once the kernels show consistent brown flecks, transfer the corn to a plate and let it rest briefly so the steam settles and the juices redistribute. The residual heat will continue to cook the kernels a touch, and resting helps prevent splatter when you slice them off. Do not skip this rest, as cutting into piping hot corn can lead to steam loss and a drier bite.
In a large bowl combine the mayo garlic and lime zest and juice: When you whisk mayo , garlic , and lime together you release an aroma that is creamy, sharp, and citrusy; this acts as the dressing base. Whisk vigorously until smooth so the dressing coats the kernels evenly. If the mayo is too cold it can clump, so stir until silky. A common slip is under-mixing which leaves pockets of unincorporated mayo.
Slice the kernels off the corn and add to the bowl along with the scallions: Slicing the kernels produces a satisfying sound as they release from the cob, and seeing the bright yellow kernels fall into the bowl is rewarding. Work on a rimmed plate to catch stray kernels, then add the chopped scallions immediately so their fresh sharpness infuses the warm kernels. One pitfall is cutting too close to the cob which can introduce woody bits into your salad; aim to slice cleanly down the sides.
Stir to coat then add the cheese cilantro smoked paprika jalapeño and salt: As you stir, the dressing clings and you will notice the salad becoming glossy and fragrant, with flecks of green and red appearing. The crumbled cheese will begin to soften slightly from the residual warmth, integrating with the creamy dressing. Sprinkle the smoked paprika for a gentle warmth and add diced jalapeño to taste for heat. Avoid over-salting at this point because the cheese will contribute salt; a common mistake is assuming you need more salt after adding cheese, so taste before adjusting.
Season to taste and serve immediately or chill until ready to serve: Take a small forkful to evaluate balance; you should perceive smoky, creamy, salty, herbal, and a touch of heat all at once. Serving right away showcases the warm, slightly smoky kernels, while chilling lets flavors meld for a cooler, more cohesive salad. If chilling, cover tightly to keep textures from drying out, and retaste before serving as cold temperatures mute flavors and may need a final squeeze of lime or a pinch of salt .
