Cooking just for two---or even one---is often touted as being difficult. Personally, I never understood why. But a lot of people do find it hard. So I'm sure a book like that is helpful.
There are other alternatives. Many cooking & recipe sites, nowadays, include conversion links. You put in the number you want to cook for, and the program automatically adjusts everything.
We're empty nesters ourselves. But I continue making full recipes. Then I put up our own frozen dinners. So, each time I cook, we typically get six meals.
I start with a microwavable version of foam plates. The meal gets laid out on it, and is then covered first with plastic film (squeezing out as much air as possible), and then heavy duty foil. Works like a charm, and we always have meals ready to go. Just need reheating---which is about the only use my microwave gets.
Have you noticed, by the way, the change in "serve #" amounts? Used to be that six servings was standard for recipes. Now, more and more, it's down to four---supposedly to reflect the changed family sizes in American homes.
