This is a wonderful meal on an autumn day, served with a crisp green salad. The slow-cooked chicken is packed full of flavour and the crust - gluten-free, rich and corny - makes for a welcome (and lighter) change to a heavier mash. You can make the chicken well in advance if you want to get ahead: it keeps in the fridge for up to 3 days or can be frozen for 1 month. You want it to go into the oven defrosted, though, so it will need thawing out of the freezer. The batter needs to be made fresh and spooned on top of the chicken just before the dish gets baked, but it then can just go back in the oven. It can also be baked a few hours in advance - just warm through for 10 minutes, covered in foil, before serving. I love the combination of the chicken and the corn, but the chicken also works well as it is, served on top of rice, in a wrap or with a buttery jacket potato.
