Heat the butter in a skillet until melted and foaming.
Add the onion and garlic. Sauté until soft and transparent.
Add the corn kernels and red bell pepper, salt, cayenne, and freshly ground black pepper.
Sprinkle on the flour (this helps to thicken the mixture) and stir.
Add the half and half. Stir well to combine the ingredients. Cook for 3 - 4 more minutes to heat through. Season to taste with salt and pepper.
Sprinkle the chopped parsley or cilantro on top and serve.
Notes
TIP: I like to place a plastic cutting mat or sheet of parchment paper inside a sheet pan to catch any wayward flying kernels.TIP: Remember to start butter in a cold pan - you don't want it to burn.NOTE: If you want a richer dish, use heavy whipping cream.
