Practical

Consumer tips

  1. 1

    If cooking Cuttlefish, either sear it very fast or braise it very long; the middle ground makes it rubbery.

  2. 2

    Look for Atlantic Cod if you want a slightly sweeter, flakier fillet, but both Pacific and Atlantic are great lean options.

  3. 3

    If you have high cholesterol but want the minerals from Cuttlefish, pair it with fiber-rich vegetables to help mitigate cholesterol absorption.

  4. 4

    Choose frozen Cod without additives; previously frozen fish is often fresher than what sits at the counter.
