The question How do you grill a perfect burger? tells me the best solution is to fry not grill, but I find frying makes such a mess I spend ages cleaning up afterwards.
So I grill burgers using my oven grill, but I think the temperature of my oven grill isn't high enough even at full gas. If I cook burgers long enough to get the outsides nice and caramelised then they are too cooked inside and have gone a bit dry. Even preheating the grill for an extended period doesn't help much. Grilling outside on a barbeque works and doesn't mess up my kitchen but it isn't a practical everyday solution.
So my question is how to cook a perfect burger in my kitchen without making a mess? I'm open to all suggestions, though obviously I already have some ideas and top of the list is to use a George Foreman grill or something similar. Do George Foreman grills get hot enough to cook burgers nice and brown without them going dry?
