To try and cook a meal, not just a dish, in 30 minutes is quite a challenge. But Jamie Oliver seems to have organized these "recipes" in such a way that it can be done. I have tried a few and have yet to complete one in 30 minutes, but most of this is due to lack of equipment or having to substitute ingredients because I cant get them easily in the country I live in.
Following his instructions is very straightforward, but I found watching the video beforehand really helped me understand the "work flow" he tries to get across in his instructions. Video does seem to be the way forward for cooking and recipes, visual and audio make so much more of an impression on us than merely the written word. I found a blog that contains three episodes of "Jamies 30 Minute Meals" and found the instructions far clearer once I had watched Jamie execute each dish.
