I purchased my edamame (soy beans) frozen, in their pods.
Prep was super simple. Boil some water, add the frozen pods, boil for about 5-7 minutes, drain and rinse with cool water then pop or squeeze the beans from their pods into a bowl...Enjoy!
Kids would have a blast helping with this activity and may even enjoy eating them more knowing they had fun freeing the beans from their pods. It's so easy, they just slide right out.
