Garlic: Freshly minced garlic cloves have an unbeatable flavor that will make this simple fish recipe really shine. Use fresh cloves whenever possible, or jarred and frozen garlic both make great substitutes. In a pinch, you can use garlic powder.

Lemon Juice: The bright citrus flavor of lemon brings out the buttery and briny flavor naturally found in the cod. For this recipe, freshly squeezed fresh lemon juice is the best choice because you will also need the zest; plus, zesting the lemon first allows it to release all its delicious juices.

Lemon Zest: Citrus zest contains so much potent flavor that just a little bit brings a vibrant note that cannot be beaten. Be careful not to scrape too hard or go too deep when zesting a lemon. The top yellow layer of the peel has the best flavor, but the white pith underneath can be bitter.

Parsley: Parsley has a wonderful herbaceous aroma and leafy green appearance that makes it ideal for garnishing. Be sure to wash your herbs very well before using them.
