I need to make a large creme brulee, not in individual ramekins. I want to use a large 1 or 1 1/2 flat quart dish. Basic recipe, or a little kicked up. Been searching the net for a recipe that doesn't specify individual ramekins and having no luck. Is there a difference if I just put the whole recipe in a large flat quart dish vs. small ramekins? Can I use the same recipe? Thanks.
