Description
A decorative technique where intricate designs are pressed into pliable sugar sheets for ornamental confectionery.
Technical
Involves controlled cooling of sucrose syrup to form a malleable glass (amorphous solid) with 2-3% residual moisture, allowing plastic deformation before recrystallization occurs. The process exploits the glass transition temperature range of sugar (60-70°C) where it behaves viscoelastically.
Culinary Significance
Creates edible decorations with architectural precision, essential for showpieces and haute patisserie presentation.
