Ingredient weight chart

What density means when you are baking

Density is simply how much mass an ingredient packs into a given space, and in a kitchen it is decided by two things: how heavy the material itself is, and how much air sits between the pieces. Panko is the clearest case of the second. It is made from crustless bread dried into large flat flakes, so a cup of it is mostly air and weighs about 50 grams. Ordinary dried breadcrumbs are ground fine, settle into the gaps, and come in at roughly double that from the same starting material.

Honey sits at the other end for the opposite reason. It is a dense liquid with no air in it at all, so a cup weighs about 340 grams, more than a cup of water. This is also why swapping honey for sugar by volume goes wrong: a cup of each differs by well over a hundred grams, and the honey brings water with it.

The practical consequence is that measuring by volume carries an error that measuring by weight does not. For soups and stews it does not matter. For bread, pastry and anything where the ratio of flour to liquid decides the texture, it is the difference between a tender crumb and a dense one. The figures below let you switch either way; the full method is on the methodology page.
