Overview: This week's show was all about meals that may not be ready in a flash, but which are low on preparation and effort. The chicken and ribs go into a bag to marinate before being put to roast along happily in the oven. The tagine improves with a couple of days' rest, meaning last-minute panics are avoided. And for dessert, the exotic trifle takes moments to throw together, then can just sit in the fridge until you're ready to tuck into the feast.
