Thoroughly zest one lemon to obtain 1 teaspoon of zest and set aside.

Squeeze fresh lemons through a fine-mesh strainer to collect 1/2 cup of juice, ensuring no seeds are present.

Combine the frozen strawberries, fresh lemon juice, lemon zest, cold water, honey, and ice cubes in a high-speed blender carafe.

Secure the lid and process the ingredients on the highest speed setting for 60 seconds or until the texture is uniform and aerated.

Stop the blender and taste for balance, adding additional honey if a sweeter profile is desired.

Portion the smoothie into two chilled glasses and garnish with a lemon wheel or fresh strawberry if preferred.
