This is a recipe from the Azores Islands (just off the west coast of Portugal). They're known for growing some of the world’s best pineapples that pack quite an intense citrus flavor. Today, the Azorean island of São Miguel hosts more than 6,000 pineapple greenhouses (something that’s unique to the Azores) which raise the majority of the pineapples sold in the Azores and Portugal. This recipe features fresh São Miguel pineapple and locally grown lemons and limes, and it results in a refreshing, tangy pitcher of the best lemonade available.
Make a simple syrup by combining the sugar and 1 cup water in a medium saucepan over medium heat, stirring frequently, for 5 minutes or until the sugar is completely dissolved. Let cool.
In a large pitcher, whisk together the cooled simple syrup, lemon juice, pineapple juice, lime juice and 5 cups water. Add the sliced lemon, sliced lime and mint leaves, and stir gently. Place pitcher in the refrigerator to chill until ready to serve.
