Mexican elotes

Step 1

To make the crema, mix the soured cream and double cream with 1/4 tsp salt. Cover, and leave at room temperature for 3 hours. Keep out if using straight away, or chill and keep for up to 3 days.

Step 2

Light the barbecue, and wait until the coals are grey and the flames have died down. Meanwhile heat the butter with the garlic and a pinch of cayenne in a small pan until melted, and season. Char the cobs for 10-15 minutes, continually turning, until the kernels are tender and lightly charred all over.

Step 3

Brush the cobs with the melted butter, then spread the crema over evenly. Crumble over the cotija and sprinkle with a good pinch of cayenne pepper. Scatter with coriander and serve with lime wedges to squeeze over.
