Standard measurements on a page cannot convey the chemical transformation that occurs when mechanical force incorporates air into protein strands. Whipping egg whites introduces microscopic air bubbles, while sugar stabilizes those bubbles by dissolving into the surrounding liquid and increasing viscosity. Achieving a satiny texture requires absolute cleanliness in equipment; even a microscopic trace of fat from a bowl or whisk will prevent the proteins from bonding and trapping air effectively.
Store finished puffs in an airtight container at room temperature for up to one week to maintain their brittle crunch. Freezing baked meringue is generally discouraged because ambient moisture in the freezer degrades the crisp exterior upon thawing.
