I don’t have Sonic’s Cherry Milkshake - I have this one:
Sonic’s Cherry Lime Ade
1 lg Lime (if you like limes use 2)
2 tb Cherry syrup
Lemon/lime soda (Sonic uses Sprite)
Half of lime and a Maraschino cherry – for Garnish
Mix together and serve over ice. Garnish with half a lime and a maraschino cherry.
Only about 15% of my recipes are categorized on this computer - I’m working on it slowly (too many to do!) but I am almost positive that I have it. When I find it I will post it for you.
