We have inherited an Aga in our new house, and I'm still getting to grips with it! Have some family coming over at the weekend and was going to do some slow-roasted lamb shanks. In conventional oven I'd cook the for about 2 1/2 hours, but how long in the simmering oven? Have read recipes that say the same time as I would in my old oven, but others say 8 hours/overnight in the simmering oven, but that sounds like they'd become horridly dry! Any advice aga owners?
