- Bring approxiately 4 quarts of water to a boil and add the macaroni. Cook until VERY soft, about 15 minutes. 
- Drain the macaroni and return to the pot. Add the 1/4 cup vinegar and stir until the macaroni is well coated. Let cool. 
- While the macaroni is cooling, combine the mayo, milk and brown sugar. Mix well. Add any desired salt and pepper. 
- Pour this mixture over the cooled macaroni and mix until well blended. 
- After mixing, add in the green onions and carrots. I usually save a little of both to add as a garnish on top. 
- This salad is best if chilled for 2-4 hours before serving.
