The amount of salt to add to one cup of flour for bread can vary depending on your personal taste preferences and the specific bread recipe you are using. However, a common guideline is to add about 1 to 1.5 teaspoons of salt per one cup of flour.
Keep in mind that salt plays an essential role in bread-making. It enhances the flavor of the bread, helps control yeast activity, and contributes to the overall texture and structure of the finished loaf. If you prefer a less salty taste, you can start with 1 teaspoon of salt and adjust according to your taste in subsequent batches.
It's also worth noting that some bread recipes might call for a little more or less salt, so always follow the specific recipe you are using for the best results. Additionally, if you are making a larger batch of bread, you can scale the salt accordingly.
