Hello everyone - I also enjoyed the chilled pear soup on an Enchantment of the Seas cruise by Royal Carribbean. I found a recipe that comes about as close as you can get to RC's version. This is taken from Friendly Foods by Bro. Ron Picarski
8 pears - peeled, cored and diced
2 cups water
1/4 tsp sea salt
4T brown rice syrup (I've used sugar in mine - I don't care for brown rice syrup flavor)
1/2 tsp fresh or powdered ginger
1/4 tsp anise extract (optional - I don't believe it was in the RC version)
Bring pears, water and salt to a simmer. Add rice syrup and ginger. Simmer 3 minutes more. Allow to cool. Puree and serve chilled.
I believe this would be considered an appetizer - that was where it was listed on the menu. Enjoy, folks.
