Regular oranges work just as well, but they won't impart the same fiery sunset color.

Ingredients
Preparation
Step 1
Finely grate enough peel from oranges to measure 1 1/2 tablespoons. Combine 1 1/4 cups water, sugar, and 1 1/2 tablespoons orange peel in heavy medium saucepan. Stir over high heat until sugar dissolves and syrup boils; remove syrup from heat.
Step 2
Cut all peel and pith from oranges. Working over bowl to catch juices, cut between membranes to release orange segments. Discard any seeds. Transfer orange mixture to processor; puree until smooth, about 30 seconds. Measure 2 1/3 cups orange puree and mix into orange syrup (reserve any remaining puree for another use). Cover orange mixture; refrigerate at least 6 hours and up to 1 day to blend flavors.
Step 3
Process orange mixture in ice cream maker according to manufacturer's instructions. Transfer to container; cover and freeze. (Can be made 2 days ahead.)
