Bake him a gingerbread
Little touches like home-baked bread and cake, a thermos filled with old-fashioned soup, or a small jar of his favourite salad, make a box lunch much more like a meal at home.
The fact is, every hard-working man in our war industry deserves and needs heartier, tastier food than the average box lunch offers. The gingerbread pictured on this page is one part of a perfect answer. It’s light, velvety satisfying. It is well-blessed with homemade taste.
Try this tested recipe. It will make sufficient gingerbread for several generous lunch box servings plus enough for two dinners for a family of four. And it’s easy to bake when you use home-type flour like Kitchen Craft.
