Someone linked here to an article about inflation in US some time ago. It was talking about an older lady that couldn't make cookies any more because the pre-made cookie mix she uses has different size now and her recipe doesn't work. It was just mind boggling to me. Cooking and baking is not that difficult. I'm just an IT guy and I can bake. You just follow the recipe, it's not rocket science. If older generations can't follow a cookie mix recipe I don't even want to imagine what young people eat.
And more on the topic. I do check ingredients on most things I buy and if I can't find something without preservatives I just make it. Yesterday I was making tortillas for tacos because the ones in stores have lots of additives. It's really simple but definitely more difficult than cookie mix recipe.
