Homemade lemonade just got better. When you roast the lemons, the sugars in the fruit begin to caramelize and add a deep and intense flavor that lends perfectly to lemonade.
Preheat the oven to 375°F and line a 9x9-inch baking dish with parchment paper and set aside.
Wash the 5-8 lemons, then slice them in half and place them in the baking dish.
Roast the lemons for 25 minutes.
Remove from the oven and let the lemons cool for 10 to 15 minutes.
Lemonade
Use a citrus press to squeeze the juice out of the roasted lemons into a liquid measuring cup.
Strain the roasted lemon juice by pouring it through a fine-mesh sieve or use it as is for a pulpy lemonade. Cool to room temperature before using.
In a pitcher, combine the cooled roasted lemon juice, 1 cup simple syrup, and 4 cups cold water.
Slice 1 lemon into 8 slices and add 4 to the lemonade, then stir to combine.
Serve in a highball glass with ice and garnish each with a lemon slice. Serve with a straw.
Notes
You can use 1 cup of strained roasted lemon juice or 1¼ cups of unstrained lemon juice if you prefer it with pulp.
This recipe can also be used to make traditional lemonade, simply skip the roasting and use fresh lemon juice. However, you will need about 7 to 8 lemons to get the amount of lemon juice needed instead of the 5 used when roasting.
