Corn
For corn kernels: Heat a large cast iron skillet over medium-high heat. Melt 2 tablespoons of butter or olive oil in the skillet and add corn, stirring to coat. Cook, stirring every few minutes, until the corn is slightly charred and golden; 8-10 minutes. Transfer to a bowl and pop in the fridge to cool for at least 10-15 minutes.
For corn on the cob: Heat a grill or grill pan at medium-high heat. Brush the ears with melted butter or olive oil and sprinkle with salt. Grill for 8-10 minutes, turning a quarter turn every couple of minutes until char marks form on all sides.
