Steps
1
Make the syrup: To a medium pot, add the mango chunks (plus any juices), sugar, and ½ cup water. Heat on medium and simmer 4–6 min., until mango is very soft and begins to break down, mashing fruit with the back of a spoon occasionally. Remove from heat and let cool briefly. Strain mixture through a fine-mesh sieve into a jar, pressing with back of spoon to extract as much liquid as possible. Discard any solids. Stir the Tajín into syrup. Let cool to room temperature, then cover and store in the refrigerator for up to 1 week.
2
To make the dirty soda, run ½ lime around the rim of 4 tall glasses. Place the Tajín onto a small plate. Dip rim of each glass into Tajín to evenly coat.
3
Fill glasses with ice. Add 1 cup cola and 2–3 tsp mango syrup to each glass, stirring to combine. Slowly pour in 1–2 tbsp half & half per drink. Cut remaining lime half into wedges and use to garnish glasses.
