Char the corn cobs on a grill, barbecue, or hot pan until nicely blackened and smoky.
Carefully cut the kernels off the cobs and set aside to cool slightly.
In a large bowl, add the corn kernels, jalapeños, spring onions, and coriander.
In a separate bowl, mix together the mayonnaise, minced garlic, lime juice, chilli powder, and salt until smooth.
Pour the dressing over the corn mixture and toss well to combine.
Gently crumble in the feta cheese and mix through last.
Serve immediately or chill for 15–20 minutes for even better flavour.
