How To Caramelize Onions

Combine a blend of about 2 tablespoons of olive oil and 2 tablespoons of unsalted butter per 4 cups of thinly sliced onion.

Brown the onions slowly and steadily in the melted oil/butter over medium heat for about a half hour.

Toward the end, add a generous pinch of salt. They should be a reddish brown color.
