I have cooked these lots this summer both on the BBQ and in the oven, but in the oven I cook at 150c and leave in for one hour or longer if I have time, they are so thick and gooey. Sometimes I wizz them in the blender and put into Pasta, also used them for the Chicken Cacciatore found on here. LOVELY !!!
