Step 1

Thinly slice the celery ribs. Measure out the celery leaves. Thinly slice the red apple.

Step 2

In a medium bowl, whisk together the white wine vinegar, Dijon mustard, maple syrup or sugar, and kosher salt. Gradually whisk in the olive oil one tablespoon at a time.

Step 3

In another bowl, toss together the celery and celery leaves with the apple, dressing, and Parmesan cheese shavings. Serve immediately or refrigerate until serving. This tastes best the day of making, but you can refrigerate leftovers for a few days (refresh them with a little vinegar or salt if necessary).
