Seems like times have changed and before there were so many bigger families living in big houses, and now there are more single people and single parents. I just am going from my experience. Also the population has a large group of 'baby boomers', so older people many of them looking for healthy recipes.
My sister, was an editor at Reiman Publications that was bought out by Reader's Digest, I believe they were or have looked at a new magazine for cooking for smaller households. I think it was cooking for 2. (I looked it up, it was in 2005, cooking for two)
In any case, I've gone from my childhood home of cooking for 6, to married with kids for 5, now single and renting rooms with an almost grown up kid so 3 of us to now with my son moving back, 4 of us. I think it is easier to cook for more people than for less and when I'm back to 1 or 2 people, I'm not used to cooking small meals--so I tend to skip cooking. My grocery list is off, I can't get good discounts on volume when I'm not cooking in volume and I tend to cook large on the week-ends and freeze things for warming up later or for lunches.
The demographics of households are changing, and it's changing the way we cook. I wish we did have a forum of 'cooking for 2'--35 ways to use a rotisserie chicken, how to have salads without them becoming boring (additional ingredients used in other main courses perhaps), OAMC--once a month cooking--so meals are available on the weekday after work, 15 ways to make ground turkey meals (or ground beef), packing lunches by making 20 sandwiches that can be frozen and tips about that for variety, packaging things bought in bulk, tips --like not expecting a small family to eat the same dish night after night, how to package things for the freezer and what will freeze well and not degrade. More healthy recipes, casseroles and heart healthy casseroles, and low carb soups (get your 3 cups of veggies per day), things that are high in nutrition/dollar and per calorie (organics).
Even though I'm blessed to have 4 people to cook 'with and for', I'm very aware of going through times where it's just me or just me and one other person and that makes cooking more difficult.
I remember when my grandmother on my dad's side lost her husband-my grandfather. She stopped cooking and started eating what tasted good--donuts. Over time, she developed a B vitamin deficiency, then cancer and it overtook her. I think as we age our taste buds change and her's did, and she 'got by' instead of investing in nutrition for herself. I hope I'm smarter and do better than that for myself and my family. (okay that was as much of an emotional plea as you are going to see)
I just think times are changing, households aren't as large and they are aging. Something to meet those needs might be nice too.
I'm supportive of a forum for 'cooking for two'.
