My very favourite mild is the result of a cockup. I'll post the recipe when I'm back at Mission Control, but the cockup concerned the hops. I was trying a new recipe and had intended to use admiral, but wasn't happy about the smell of half-used pack so I threw them away and reached for another bittering hop. Somehow, I got hold of Harlequin and bittered with that. It's amazing, I would never have imagined that harlequin would go with the light roast flavours and that it would still have a significant presence without any late additions. In fact I've quite abandoned my earlier recipe, which I must resurrect and remind myself what it tasted like.
