FAQ and Cooking Tips

How to store fresh Chinese water spinach

Do not remove the water spinach from the packaging. You can store it in the fridge in the crisper drawer of your refrigerator for up to 4 days.

Can you store leftover Chinese water spinach stir fry?

I do not recommend it. Spinach contains a high amount of iron. Every time you reheat spinach, it oxidizes the iron present in spinach, which releases dangerous free radicals that can cause health issues.
