What You Need to Know
Agar fluid gels form when agarose polymers crosslink at concentrations below 1%, creating a fragile network that breaks under shear stress but reforms at rest. The gel undergoes syneresis minimally due to agar's high hysteresis.
Enables precise plating of liquid sauces that hold shape briefly while remaining spoonable, bridging textures between foams and traditional gels.
