If freezing fresh pineapple or melon, cut it into small chunks, spread in one layer, and freeze for at least 3 hours.
Measure the frozen pineapple, frozen strawberries, ginger, sea salt, lemon juice, homemade coconut milk, and filtered water. Keep the coconut milk and water separate until loading the blender.
Put the frozen pineapple, frozen strawberries, ginger, and sea salt into the completely dry Ninja BN801 pitcher first.
Add the 1/2 cup homemade coconut milk, 3/4 cup filtered water, and fresh lemon juice. Seat the pitcher securely on the base.
Blend on low, then increase to medium-high, for a total of 40 to 50 seconds, until no large fruit pieces remain and the smoothie is uniformly pink-coral with fine berry flecks.
If an air pocket forms, turn the machine off, remove the pitcher from the base, stir once with a wooden spoon, remove the spoon, replace the lid, and finish blending.
Pour evenly into two glasses and serve immediately between meals.
