They use better ingredients. You pay for that.
But nothing is as good as home-made.
I went to elementary school across the street from a commercial bakery - and this was back in the 1950s. The smell was wonderful - but even then it was always somewhat ‘off’, compared to the smells of my Grandmother’s home baking.
You just can’t pull off the same quality and freshness in large-scale commercial baking, as you can at home.
Yes, but there’s something unique. Where I grew up, there were several mom and pop bakeries. And they all had the same unique aroma. I don’t mean like yeast bread baking smells. I can “taste” the aroma in the brownies or the cookies. Maybe it was pure vanilla, or meringue powder. I use real butter, real vanilla, etc., but I don’t end up with the same aroma when I bake. And a place like Paneras doesn’t have it, either. Oh well. Just another one of life’s little mysteries.
