Consumer tips

  1. 1

    Always boil flat beans for at least 10 minutes to destroy harmful lectins; steaming alone may not be sufficient.

  2. 2

    Snap the ends off snow peas and pull the string to make them more enjoyable and safer to eat raw.

  3. 3

    Buy organic snow peas when possible, as the edible pod is directly exposed to pesticides.

  4. 4

    Blanch flat beans in ice water after boiling to keep them vibrant and tender for salads.
