Lemon Meringue by Demeter is a bright and bold full-bodied lemon scent without any of the bitterness or shrillness that lemon can have. It has creamy vanilla undertones without becoming sugary or sweet. The fresh lemon cream is the star of this beautifully balanced fragrance. The chemistry of Meringue is quite fascinating. When egg whites are beaten, some of the hydrogen bonds in the proteins breakdown, causing the proteins to "denature", or unfold and change shape. This change in structure leads to the stiff consistency required for meringues. The addition of cream of tartar causes the proteins to change even more, helping to create the desired firm peaks.
