I've done a roast in the slow cooker - thanks Trav! - and I've got some sweetcorn in the fridge, still all wrapped up in its leaves. I've nuded it up, and now I wanna roast it so its a bit brown, and all buttery and salty. How do I achieve that? Just stick it in the oven for a while, or fry it on the stove? I don't have a grill
