Grilled Corn Salad

When Canadian sweet corn hits the markets in late summer, this is the salad to make. Charring the cobs on the grill turns their sweetness smoky and deep, and tossed warm with tomatoes, peppers, herbs, and a squeeze of lime, it’s the side that steals the barbecue. It’s bright, a little smoky, and tastes like the best week of summer.

Char is the flavour

Grilling is what sets this apart from an ordinary corn salad — the browned, caramelized spots on the kernels bring a toasty sweetness that boiled corn just doesn’t have. Get the cobs over high heat and turn them until they’re charred in patches. No grill? Blister the kernels in a screaming-hot cast-iron pan or under the broiler.

Grill the cobs naked, not in their husks. Husk-on steams them — useful for tender corn, useless for char. You want the kernels in direct contact with the grate, turning every couple of minutes until they’re spotted dark brown to black in patches. Blackened patches, not a uniformly blackened cob.

Buy corn as fresh as you possibly can. Sweet corn begins converting its sugars to starch the moment it’s picked, and the difference between a cob bought the morning it was cut and one that’s been sitting three days is easy to taste. Canadian sweet corn runs from roughly mid-August through September — this is a recipe with a short, excellent window, and it is genuinely not worth making in February.

Look for tight green husks, moist-looking silk, and kernels that feel plump through the husk. Dry, straw-coloured silk means it’s been sitting.

Cutting the kernels without losing half of them

Stand the cob in a wide bowl rather than on a board, and cut downward — the kernels land in the bowl instead of skittering across the counter. Setting the cob in the hole of a bundt tin works even better if you have one.

Then run the back of the knife down the stripped cob to press out the milky liquid left behind. It’s sweet and starchy and it makes the dressing cling. Most people throw that away.

Toss it warm

Cut the kernels off and dress the salad while the corn is still warm — it drinks up the lime dressing better and everything comes together. Use the ripest tomatoes and peppers you have; this is a garden-glut salad.

Warm, not hot. Straight off the grill it will wilt the herbs and cook the tomatoes slightly; a few minutes’ rest first is right.

Bright and balanced

Lime, olive oil, and a pinch of chili keep it fresh and lively against the sweet corn. Salt generously — corn loves it.

Salt matters more here than in most salads, because corn is sweet and sweetness without salt reads as bland rather than sweet. Taste, salt, taste again — you’ll almost certainly want more than the first instinct.

When it doesn’t come out right

• No smoky flavour. Not charred enough, or grilled in the husk. Push it further than feels right.
• Chewy, tough kernels. Over-grilled, or corn that was past its best when bought.
• Starchy rather than sweet. Old corn. Nothing fixes this after the fact.
• Watery at the bottom. Tomatoes not seeded, or dressed too far ahead. Seed them and dress closer to serving.
• Bland. Salt, then more lime. In that order.
• Herbs gone limp and dark. Tossed in while the corn was still hot.

Storing it

It keeps 3 days in the fridge and is good cold, though it loses the just-charred aroma after the first day. Refresh leftovers with a squeeze of lime and a little fresh herb rather than serving them as-is.

Don’t freeze the finished salad — the tomatoes collapse. Do freeze plain grilled corn kernels, though: char the cobs, cut the kernels off, cool, and freeze flat in bags for up to a year. They go straight into winter soups, chowders and this salad again, and they carry that smoky flavour with them.

If you’re facing a real corn glut, the proper answers are freezing or dehydrating it. Corn is a low-acid vegetable — never water-bath can it, and use a tested pressure-canning process or a tested corn relish recipe if you want it in jars.

Make it yours

• Cheesy: crumbled feta or cotija, elote-style.
• Creamy: diced avocado, or a spoonful of mayo for a Mexican street-corn feel.
• Hearty: black beans and grains to make it a meal.
• Herby: cilantro, basil, or plenty of green onion.
• Smokier: a pinch of chipotle or smoked paprika in the dressing.
• Sharper: thin-sliced red onion soaked in cold water first.

Serve it warm or at room temperature alongside anything off the grill. It’s a five-minutes-of-charring, ten-minutes-of-chopping side that punches far above its effort — and the highlight of corn season.
