What You Need to Know
Involves hydration and melting of collagen-derived gelatin (typically 200-250 Bloom strength) in a liquid medium (water, stock, or fruit puree) with sugar (40-60% w/w) and often pectin (0.5-1.5%) for improved sheen, followed by precise temperature control (35-45°C) during application to ensure even coating without premature setting.
Provides both visual appeal and protective coating, preventing oxidation while adding minimal flavor interference.
