Peel the mango and cut the flesh away from the pit. Peel the banana. Rinse the baby spinach briefly in a bowl of cold water and let it drain — supermarket spinach is usually pre-washed, but a quick rinse never hurts.
Frozen mango works just as well as fresh — simply let it thaw in the refrigerator overnight, or use it straight from frozen for a colder consistency. Frozen banana (freeze it in slices) makes the smoothie creamier and colder without needing ice.
If you want to work in even more spinach: up to 80 g for 2 servings keeps the mango character dominant. Above that, the green leafy taste increases noticeably. A teaspoon of lemon juice brightens the color and rounds out the flavor — optional, but recommended.
