Wonderful and refreshing. I froze it in an ice cream maker so it turned out smooth and delicious. I definitely recommend using one. I just approximated the amounts. About 2 cups mostly freshly squeezed orange juice and the rest store bought, 1/2 cup freshly squeezed lemon juice. I think I used less white sugar than called for but I'm not sure and around 3 cups of water. Be careful not to go over on the orange blossom water amount but this is definitely an ingredient you mustnt leave out. I added the additional option of finely grated lemon peel which was good. I will make this again.
The advice to use trays is good because if you leave it in a bowl this stuff does not want to freeze! Due to the freezing issues, I ended up using this as a cordial as it is quite strong tasting. Don't try to do without the orange blossom water - this is what makes the recipe.
Delicious and refreshing. And particularly good after a spicy meal. Thank you, Blue Moon.
