Tips
- Cooking the Cauliflower: For the best texture, steam the cauliflower instead of boiling it. Steaming preserves more of its flavor and helps keep the florets intact.
- Adjusting the Dressing: If you prefer a tangier taste, add more apple cider vinegar or Dijon mustard. If you want a creamier texture, increase the amount of mayonnaise.
- Season to Taste: Taste the salad before refrigerating and adjust the salt and pepper as needed. It’s better to slightly under-season initially and adjust after chilling.

- Dairy-Free Option: Use vegan mayonnaise to make this salad dairy-free. You can also substitute a dairy-free yogurt for some of the mayonnaise.
- Herbs: If you don’t have dill, try fresh parsley, tarragon, or thyme as a substitute.
