This book by the duo that wrote Desperate Dinners is more interesting because they are not relying nearly as much on packaged sauces and such to provide the foundations for the meal.
It has plenty of good tips for time management, their phased and flexible recipes give good pointers on prepping meals in steps to make it all manageable, and their style is much more casual overall than Perfect Party Food. No elaborate set ups here for a party of 20.
However, there are plenty of ideas for when 20 people burst in on you unannounced, which has been my lot for the last few Friday nights when Hannah and her friends have been nearby and set up base camp here.
Perhaps this could be looked at as the everyday entertaining guide, which is just what I need.
