If you loved the mint lemonade at Yum Restaurant, here's the copycat recipe to recreate that lemony minty goodness in your own kitchen!
Combine 1 cup water and 1 cup sugar in a saucepan.
Bring to a boil, stirring intermittently until sugar dissolves completely.
Remove from heat and allow to cool to room temperature.
Put mint leaves, lemon juice, salt and 1/2 cup + 2 tbsp simple syrup in a blender.
Blend, starting at low speed, then increase to high until the mint leaves are finely blended.
Add four cups water, then blend again until well combined. Check for sweetness. Add more simple syrup if needed.
Strain into a jug and chill in fridge until ready to serve.
Leftover simple syrup can be stored in an airtight container in your fridge.
If your blender can handle it, you can blend ice cubes in with the water so that you can serve it right away. Just make sure you decrease the water amount to compensate, or else it will water down the flavor.
