Shuck and quickly rinse all ears of corn. Wrap each corn with aluminium foil tightly.
On a BBQ heated on medium to high heat cook your wrapped corn for 15 minutes. Rotating on each side throughout.
Remove the foil (carefully it will be hot!) and place the corn on the cob back on the grill for about 5 minutes. Rotating to every side. We are just looking to get a bit of colour on them.
To make your drizzle add your mayo, water, lime juice, finely chopped cilantro, garlic powder and pepper to a bowl and mix together.
Prepare your avocado by finely dicing as small as you can get it.
Now it's time to top your corn. Give a generous drizzle to each corn and top with your avocado cubes, sriracha and chili flakes.
Notes
Pro tip: You could also top these with jalapeno pepper, smoked paprika or taco seasoning.
