My favorite part about this soup is the toasted pine nuts which I toast for only a minute or two in a dry skillet the nutty aroma reminds me of Sunday family dinners and my grandmother always had a bowl on her table
Storage Tips
Let the soup cool fully before transferring to an airtight container it keeps in the refrigerator for up to three days and reheats gently on the stove you can freeze it without the toppings for two months and reblend after thawing if texture changes
Ingredient Substitutions
If purple cauliflower is unavailable white or orange will work just as well but the color will be different use leek instead of onion for a milder base or sunflower seeds if you do not have pine nuts do not skip the garnish as it lifts every spoonful
