🍽️ How to Eat Water Caltrops

Boil first (recommended): Boil for 15-20 minutes to soften the shell slightly
Cool completely: Let them cool enough to handle
Crack carefully: Use a nutcracker, hammer, or heavy knife to crack the shell
Remove the kernel: Extract the white, starchy interior
Peel the thin skin: Remove any thin brown skin covering the white kernel
⚠️ Safety note: The shells have sharp spines. Handle with care, use gloves if needed, and keep away from children and pets.
