Practical

Consumer tips

  1. 1

    Rinse canned Crab meat to remove excess sodium before eating.

  2. 2

    Pat Scallops completely dry before searing to get a golden crust instead of steaming them.

  3. 3

    Avoid imitation Crab, which is ultra-processed pollock filled with sugar and additives.

  4. 4

    Buy dry-packed Scallops; wet-packed are treated with chemicals that affect taste and searing.
