Fun fact before I went sleep:
Do you know why bread in countries where it isn't the main carbohydrate source (like Indonesia, Malaysia, or Japan) often tastes sweeter?
The answer lies in how it's consumed. Since their staple food is usually rice or cassava, bread isn't traditionally eaten as a side dish for savory meals. Instead, it was adapted into a snack or dessert. That's why, when the bread producer want to sell their product on these regions, they need to attract the consumer with the taste. They add butter, milk, or sugar to make it appeal to local palates.
