Description
A gelatinous dessert achieved through controlled polysaccharide extraction from Tremella fuciformis.
Technical
The process involves thermal breakdown of β-(1→3)-D-glucans into smaller branched chains, while simultaneous hydrogen bonding with water molecules creates a viscoelastic matrix. Mannose-rich glycoproteins contribute to the distinctive 'snowflake' texture.
Culinary Significance
Prized for its delicate mouthfeel that mimics bird's nest soup at fraction of the cost. Modern chefs use it as a vegan thickener for fruit soups or milk-based desserts. In traditional medicine, the hydrated gel is believed to coat mucous membranes.
Science
Primary Reaction
Polysaccharide solvation → gelation
Parameters
Temperature
°C to °C range
Maintained via double-boiler for even heat distribution
Time
3 hours
90 minutes – 6 hours
Longer durations increase polysaccharide yield but risk browning
