To make bread less dense, you can try using a combination of bread flour and all-purpose flour, kneading the dough thoroughly, allowing the dough to rise properly, and adding a small amount of sugar or fat to the recipe. Additionally, using warm water and activating the yeast properly can also help create a lighter texture in the bread.
I think the answer is adding less flour.
because it has less yeast in the recipe :)
Oil IS already less dense than water.
there is no such thing
make it less dense than the substance it is floating in.
no
Gravity ! The closer you are to the core - the higher the gravitational forces. High gravity attracts dense objects more than less dense ones.
No. Toasting simply changes the structure by removing water and causing browning through the Maillard reaction. Toast may be less dense than bread, but this is simply because there is less water - the calories will be identical.
usually
Yes. By definition, most gases are less dense than most solids. i can't think of a counter example. Plus, the gas inside a hot air balloon is superheated to make it even less dense, as heating things makes them less dense
You must toast it
The density of materials depends on the temperature.
