For more than 40 years, Sonic has worked to build its dominant position in the drive-in restaurant business and create a franchise system that offers extraordinary entrepreneurial opportunities in the quick-service restaurant industry. Sonic Drive-Ins offer made-to-order sandwiches and feature signature items such as Extra-Long Cheese Coneys, hand-battered onion rings, tater tots, and a variety of Frozen and Fountain Favorites, including cherry limeades, slushes, and a complete soft-serve dessert menu. At a typical Sonic Drive-In, the customer drives into one of 24 to 36 covered parking spaces and orders made-to-order food through an intercom speaker system. The customer's order is delivered by a carhop usually within four minutes. For a number of years, Sonic has consistently maintained strong real sales growth and industry-leading customer frequency.
Makes 1 quart
flesh of a 5 pound watermelon, cubed, seeds removed
1/4 cup lime juice, from 3 to 4 limes
2 tablespoons agave nectar
In two batches, pulse the watermelon cubes in a blender just until it looks like a chunky sauce, about 10 to 12 short pulses. Transfer pulp to a colander lined with cheesecloth set over a large pot, stirring occasionally until most of the liquid has dripped through. Transfer 3 1/2 cups of liquid to a large pitcher and reserve remainder for another use.
Add lime juice and agave nectar to pitcher and stir to combine. Refrigerate until completely cool. Serve in ice filled glasses, garnished with lime zest or rings if desired.
