Step 1

Cook macaroni according to package directions. Drain well and place macaroni in a large bowl (I like to use a tupperware bowl with a lid so I can easily refrigerate later).

Step 2

While macaroni is still hot, sprinkle on vinegar and add carrot and onion. Toss together until well combined. Allow to cool for about 10-15 minutes.

Step 3

In a separate, smaller bowl, whisk together mayo, milk, and sugar. Fold mayo mixture into the macaroni until all the noodles are evenly coated. Add salt and pepper to taste.

Step 4

Cover and refrigerate at least 4 hours (best if overnight). Gently stir before serving adding a little more milk if needed, no more than a tablespoon or two.
