I own Jamie's Dinners, Comfort Food, Save with Jamie, JO's Christmas cookbook, Cook with Jamie , Happy Days with the Naked Chef, Jamie's Food Revolution, Jamie Cooks Italy and Jamie's Meals in Minutes. There are great recipes in all of them with lots of household favourites on repeat......so very hard to recomment 1 or 2 but I'll try. One thing I do like is that I can pretty much always get all of the ingredients - there are only 2 grocery stores in my small town so some authors/books just don't work for me...yes I order things online but there is a limit to how often I will do that and it doesnt help for fresh items or "tonight's dinner"! Also - all his books seem to have good sized fish chapters.
Food Revolution (also published as The Ministry of Food) has lots of great ideas including pages where he takes a basic idea (ie carrot salad) and ups it in steps - he calls these pages "Evolution... salad" recipes. Another example is a basic stew procedure and then gives opitions such as chicken & white wine, pork & cider, beef and ale etc. This is followed with ways to dress your one pot up with different toppings. And hands down my favourite chapter is the curry chapter - homemade curry pastes and a wide variety of curries in which to use them.
Save with Jamie resonates with me as I cook for 2 but do like to prepare roast chickens and beef etc. He starts with a "mothership roast" and then provides LOTS of different ways to use the leftovers. I make lots even with out the specifc "leftover" meat on hand. There is also a great veg chapter and pages with tips for using up / preserving various fridge & pantry items. I got lots of good ideas from this one.
Tough call re: Jamie's Dinners, Comfort Food and Cook with Jamie - all 3 are great books....Comfort Food has lots of bigger projects (this is where I learned to make pasta from scratch), Cook with Jamie is full of recipes that helped me learn some new techniques and Jamie's Dinners provides lots of good weeknight options (incuding my gold standard chicken pot pie :)
I checked with EYB notes and the title on my shelf with the most comments is Meals in Minutes.....it turns out that this is not really my style of cooking and if you are not making the entire meal then you have to keep scanning through the recipe to pick out the specific ingredients / steps you need. If you like his current TV shows (15 minute and 30 minute meals) then maybe....
Note to Fyretigger - my favourite Yorkshire pudding is from JO's Christmas book...worked perfectly the 1st time and every time since :) I just read the "double whammy toad in the hole" recipe and am thinking of how to cut it back to make a great Sunday dinner for the 2 of us!
