We served this slush at Josh and Sarah's wedding reception.
I got the recipe from a lady in our ward. At the Court of Honor for one of her sons, they served this slush. I think it is from the Lion House Christmas Cookbook.
When my older kids were scouts, everyone in our ward made a huge deal about Eagle Scout Courts of Honor. They were almost like a wedding reception. It was kind of crazy. Fortunately, that tradition changed. Now they are more like a normal Court of Honor, honoring several of the boys at the same time and with only slightly more fanfare. It's much better and much easier. At the Court of Honor for one of the scouts many years ago they served this slush. It was delicious. It is very pretty as well.
