> Did people in the past make bread without sugar?
They do it in the present.
Greetings from Europe. I hold in my hand a loaf of cheap (€1.20) supermarket bread, which tastes perfectly pleasant. The little supermarket on my street moves a full shelf of this every day.
The ingredients are:
- Wholewheat flour
- Water
- Wheat gluten
- Yeast
- Malt flour (barley, wheat)
- Rye sourdough powder
- Salt
- Sesame seeds
- Poppy seeds
- Polenta
- Rapeseed oil
I have experienced the bread in the USA and it tastes like a light cake. The sugar makes it cloying to my taste. I guess it's all about what you're used to. But yes, bread without sugar is a very normal thing, and I wouldn't want sugar in mine.
Malt flour contains 6-20% of sugar according to a German source I've found, so together with its low rank in the ingredient list, it's not a whole lot of sugar.
Sugar is unnecessary but it does help the yeast so you won't need to use as much, but when there's enough sugar for bread to taste sweet you might as well eat cake.
