With Labor Day just around the corner, it’s evident that we need to talk about cocktails. This is summer’s last hurrah! It’s your last three-day weekend for a while, so enjoy every last sip of it.

Try my take on Marcella's Rosemary-Infused Lemonade to get the party started. This cocktail would make the perfect addition to your party, whether it's a huge pool party with all of your friends or a casual late-afternoon barbecue on the back patio. Either way, this lemonade makes perfect sense.

So go ahead — whip up a batch or two and have a ball with your closest local pals before school goes back into full gear and fall sets in.

Bring six cups of water to a boil in a saucepan. Remove from the heat, then add the rosemary and a pinch of salt. Cover and steep for 30 minutes. Strain into a pitcher and cool to room temperature.

Stir the lemon juice, agave nectar and 2 cups cold sparkling water into the same pitcher. Add more lemon juice or agave nectar to taste. Add the gin and stir. Serve over ice with more rosemary and/or lemon slices, if desired.
