I have been using my Le Creuset Dutch ovens and cast iron pans for over a decade and half, and have nothing but praise, admiration and utmost devotion for the brand. I cook almost everything in my Le Creusets. Last year I bought the square grill pan (and a panini press that goes with it), and the thing just does not work for me. Food sticks to it. Plus it is difficult to clean. Has anyone had similar experience? What do you recommend? What do you cook in your grill pan? Any tips, suggestions, recommendations are greatly appreciated.
