Creamy Cauliflower Soup

Cauliflower Power! My attempt at a joke. They never end with good results.

What you need:
3 tbsp butter
1 medium onion, diced
1 tbsp each, salt and pepper
4 medium potatoes, peeled and blocked
4 cups cauliflower (no stems)
6 cups water
1 cup whipping cream
1 bottle Tabasco sauce
1 tbsp celery salt

Steps:
1. melt butter over medium heat
2. add onion, cook 3 minutes while stirring, or until soft
3. add salt, pepper and celery salt, stir 2 minutes
4. add potatoes, cauliflower and water, bring to boil
5. reduce heat to low and cover until cauliflower becomes soft, about 15 minutes
6. remove solids with slotted spoon and place in separate dish.
7. mash solids with hand blender and return to original pot
8. simmer for just 5 minutes

Extras:
-goes well with Salmon, Trout and Chilean Sea Bass. It might go well with all seafood as I think about it.
-for a swell presentation, garnish individual servings with dill, chives or chopped green onions.
