- Skipping the Vinaigrette Tasting: Before serving, always taste your vinaigrette. Adjusting seasoning at this stage is important for a balanced flavor profile.
- Using Old Ingredients: Fresh ingredients make a big difference in taste. Ensure your asparagus and radishes are fresh for the best results in your salad.
