Chef John's Classic Macaroni Salad

Whisk 1 cup mayonnaise, vinegar, Dijon mustard, salt, black pepper, and cayenne pepper together in a bowl until well blended; whisk in sugar.

Stir in celery, red bell pepper, carrot, onions, and jalapeño and poblano peppers.

Refrigerate until macaroni is ready to dress.

Bring a large pot of well salted water to a boil.

Cook elbow macaroni in the boiling water, stirring occasionally until cooked through, 8 to 10 minutes.

Drain but do not rinse.

Allow macaroni to drain in a colander about 5 minutes, shaking out moisture from time to time.

Pour macaroni into large bowl; toss to separate and cool to room temperature.

Macaroni should be sticky.

Pour dressing over macaroni and stir until dressing is evenly distributed.

Cover with plastic wrap.

Refrigerate at least 4 hours or, ideally, overnight to allow dressing to absorb into the macaroni.

Stir salad before serving.

Mix 1 tablespoon mayonnaise and 1 tablespoon water into salad for fresher look.
