Watermelon supplies most of the liquid for blackberry, strawberry, and spinach. The berries add a deeper flavor and color than melon alone. Without banana or milk, the drink stays relatively light and can retain a little blackberry-seed texture after blending.

Ingredients
- 1 cup spinach
- 1.5 cup watermelon chilled, rind and seeds removed
- 0.25 cup frozen strawberries

- Put the measured liquid in the blender with the prepared leafy greens. Secure the lid and process until the leaves are finely dispersed, stopping the machine before scraping down the sides if needed.
- Add the remaining edible ingredients, including the measured fruit, nuts, seeds, or spices listed for this recipe. Blend until evenly combined. Use the machine instructions to choose a suitable speed, and stop before checking texture or scraping the jug.
- Taste a small spoonful after blending. If the mixture is too thick to pour, add cold water one tablespoon at a time and blend briefly again. Divide the base batch into 1 serving and enjoy promptly.

Tips and ingredient notes
Chill melon and remove rind and hard seeds. Begin with melon near the blades to release juice. If the drink separates after standing, stir it before deciding it needs an extra ingredient.
Wash fresh strawberries before removing their tops, then measure the usable fruit. Plain frozen strawberries are convenient when fresh fruit is inconsistent. Avoid sweetened dessert berries, which change the balance and make it harder to compare one batch with another.
Measure melon flesh after removing rind and seeds. Chilling it in advance helps produce a cooler drink without extra ice. Taste the fruit first: a bland melon remains bland when blended, even if the other ingredients improve the overall balance.
