This harvest salad combines spinach with blue cheese, walnuts, and dried cranberries. If you can't find walnut oil, olive oil may be substituted.
Ensure walnuts are spread in a single layer for even toasting; cool them completely before adding to the salad to maintain crunch. For the spinach, thorough rinsing and drying are paramount to prevent a watery salad and allow the dressing to adhere properly. If the red onion's flavor is too strong, a quick soak in ice water for 10-15 minutes can mellow its bite. When making the dressing, an immersion blender can create a more emulsified, stable vinaigrette, especially with the jam. Always taste and adjust seasoning for the dressing before pouring over the salad; the balance of sweet, tangy, and savory is key. Consider using a high-quality blue cheese for a more pronounced and complex flavor.
