How to Open Water Caltrops
The shell is extremely hard and must be removed before eating.
Because the shell contains sharp points, handle them carefully.
Many people find it easier to cook them first.
Method 1: Boiling
Place the water caltrops into a pot of water and boil them for about 15 to 20 minutes.
Allow them to cool slightly before handling.
Use a nutcracker, kitchen hammer, or heavy knife to crack the shell.
Remove the white kernel from inside.
If a thin brown skin remains on the kernel, peel it away before eating.
Method 2: Roasting
Roasting intensifies their flavor and creates a pleasant nutty taste.
Place them on a baking tray and roast at 375°F (190°C) for approximately 20 to 25 minutes.
Allow them to cool, then crack open the shells and enjoy the kernels.
