Combine the 400–450g of roughly chopped mango flesh, 65g of white sugar, 240ml of water, ⅛ tsp of fine sea salt, and the strip of lime zest in a medium saucepan. Place over medium-low heat rather than the medium heat of the cranberry and blueberry preparations — mango's volatile aromatic character, while more heat-tolerant than pineapple's, is specifically more delicate than cranberry's and benefits from the slightly lower extraction temperature that medium-low provides. Bring to a very gentle simmer and cook for 6–8 minutes, stirring occasionally and lightly mashing the mango pieces as they soften — pressing against the pan's surface to release their juice and begin breaking down the flesh. The mango should be noticeably soft and partially broken down by the 6-minute mark; by 8 minutes it should be fully collapsed with the surrounding liquid vivid, golden, and intensely fragrant. The same extraction principle applies: the volume should remain approximately the same as added, the syrup should be fluid rather than thick, and the aroma should be specifically of fresh mango — warm, tropical, and vivid — rather than caramelised or flat. Remove the lime zest strip and discard it at the end of the cooking period.

Remove the saucepan from the heat. Immediately stir in the ¼ tsp of finely grated fresh ginger. Allow to steep for exactly 2 minutes. This is the briefest botanical infusion in this entire collection, and the 2-minute limit is the most specifically critical timing in this preparation. Fresh ginger at room temperature has a sharp, raw, aromatic character from its volatile gingerols and zingiberene. In warm post-simmer liquid at approximately 80–90°C, these volatile compounds transfer within minutes — 2 minutes extracts the most volatile, most specifically aromatic fraction into the surrounding warm mango syrup at a concentration where it is below detection as a separate ginger character but provides a barely-perceptible warming dimension that makes the tropical mango flavour taste more vivid and more three-dimensional. At 5 minutes in the same warm liquid the ginger character begins to become detectable; at 10 minutes it is clearly present as ginger rather than as background warmth. The ¼ tsp quantity combined with the 2-minute steep is the specifically calibrated approach for ginger as aromatic amplifier rather than flavour contributor. After 2 minutes, proceed immediately to blending — the continuing temperature of the warm syrup will continue the ginger extraction if left standing, so the brief blend-and-strain step that follows naturally ends the infusion period.

Transfer the warm mango mixture to a blender. Blend briefly at medium speed — 20–30 seconds — until mostly smooth. The mango's soft flesh after 6–8 minutes of gentle simmering blends almost immediately into a vivid, golden purée. Strain through a fine-mesh sieve into a clean bowl or measuring jug, pressing firmly on the blended mango solids. Mango's fibrous matrix holds a meaningful proportion of its juice — firm pressing is required for the maximum syrup yield. Press until the fibrous solids feel dry. Discard the solids. Allow to cool completely.

In a large pitcher, combine 180ml of the cooled mango syrup, 240ml of fresh lemon juice, 1 tbsp of fresh lime juice, and 750ml of ice-cold water. Stir thoroughly. The dual citrus addition — predominantly lemon for the primary bright acid and a small amount of lime for the secondary tropical-citrus character — produces a specifically more interesting acid profile than lemon alone. Lime's sharper, slightly more tropical citric-malic acid combination specifically complements mango's own tropical character, contributing a secondary acid register that is tonally consistent with the mango's direction. Taste and assess carefully. The mango should be the clearly dominant flavour; the citrus brightness from both lemon and lime sharpening it into something specifically refreshing rather than sweet. Adjust: more mango syrup for stronger fruit character; more lemon up to 300ml for brightness; more lime juice up to 2 tbsp for additional tropical sharpness; more cold water up to 1 litre for lighter concentration; optional simple syrup only if the combined acidity is more aggressive than pleasant.

Refrigerate for 1–2 hours until completely cold and integrated. Stir before serving — mango juice contains natural large-molecule compounds that settle progressively, similar to the settling in the watermelon and pineapple lemonades. Fill glasses with ice. Pour the chilled mango lemonade over the ice. Garnish with a lemon slice and slices of fresh mango. Serve immediately.
