As a slow cooking novice, I recently bought this book along with a 1.5L sized slow cooker from Amazon. I'm enjoying the experience thus far, having tried three very tasty recipes, but wanted to give a word of warning about the "ready when you walk through the door" message which is one of the key selling points of this book. (The blurb on the back of the book, in particular, pushes this idea.)
Firstly, I've been surprised to see that the majority of these recipes have cooking times of well under 8 hours, which might be considered a minimum working day for most. None of the chicken dishes, for example, will take longer than 5 hours to cook - and that's if you've got a particularly sloooooow slow cooker. Similar story with the fish... indeed a cooking time of 2-5 hours seems to be about average throughout, with one vegetarian recipe needing just 30 minutes! Also a good many of the recipes need to have extra ingredients added part-way through cooking, which isn't going to be convenient if you're out. Similarly, some recipes require the temperature to be reduced from high to low after the first hour of cooking, which has to be done manually if (like mine) your cooker doesn't have an auto-adjust facility. Finally, while the recipes are easy to follow, I'm finding that it's not unusual for me to be spending half an hour or more measuring and chopping and browning ingredients before adding them to the slow cooker.... no problem when I've got the time, but not something I fancy squeezing in before a weekday commute into London.
And before someone suggests it, yes, some slow cookers do come with timers (mine doesn't, as it happens) but I'm not sure whether leaving a pot of meat or fish sitting at room temperature for hours is a good idea anyway?
As I say, I'm new to slow cooking, so imagine that this is not a fault of the recipes at all. If that's how long these dishes take to cook by this method, then all well and good, and the end result is certainly delicious. But "minimal effort" and "no fuss" and "you can now return to a ready-made, flavour-packed meal of your choice" and so on? Er, I don't think so! That's just a nifty bit of selling.
