Start by chopping ripe mangoes into smaller chunks, making them easier to blend smoothly and ensuring a bright, vibrant flavor.
Add the mango chunks, lime juice, secret ingredient, and ice cubes into the blender jar.
Secure the lid and blend on high speed for about 30-45 seconds, or until the mixture is completely smooth and icy in texture, with no chunks remaining.
Stop the blender and give the mixture a quick stir to ensure everything is evenly combined and fully chilled.
Pour the vibrant, frosty slushie into glasses, watching as it retains a thick, icy consistency and a beautiful orange hue.
Serve immediately with a straw or a garnish of fresh lime wedge for an extra touch of citrus zest.
