These orange cream popsicles take me right back to the hot summer of 1974 when I would sprint barefoot down the hot, bubbly, black asphalt on Elmcrest drive to the ice cream truck to buy a creamy, icy treat.
I discovered the recipe in my new favorite cookbook, Williams-Sonoma Family Meals: Creating Traditions in the Kitchen:
I can't share the exact (sorry) recipe from Family Meals that I used to make the Orange Cream Popsicles, but I can provide you with a link to a similar one below.
I combined high-quality vanilla ice cream with frozen orange juice concentrate in my stand mixer, poured it into this 8.5 x 11 (inches) glass pan lined with plastic wrap, froze it overnight, and sliced it into 10 rectangular popsicles, more than enough for my crew and friends:
After lifting each popsicle out of the pan, I inserted wooden popsicle sticks (also known as craft sticks) into the bottom of each one:
They melted very quickly in the 80 degree F heat, so it was lick fast or plop it into a bowl and use a spoon:
Here's a version to try, sans the egg (which is mysteriously mentioned in the instructions, but not in the list of ingredients): Homemade Orange Creamsicle.
Next time I make these, I'll skip lining the glass baking dish with plastic wrap and cover the dish with foil instead.
