Ruby Red Moscow Mule Popsicles are made with ginger beer, ruby red vodka, fresh lime juice, and grapefruit simple syrup for a frosty, boozy, summer treat!
In a very small pot or saucepan set over high heat, stir together the grapefruit juice and the sugar. Bring to a boil then reduce to a simmer and cook, stirring occasionally, for a couple of minutes until the sugar completely dissolves. Set aside to cool.
In a quart-sized measuring cup, gently stir together the ginger beer, ruby red vodka, lime juice, and 2 tablespoons of grapefruit simple syrup. Use a funnel to divide the mixture between six 3-ounce popsicle molds. Insert popsicle sticks and freeze until solid.
Notes
If you can't find a ruby red grapefruit, you may use regular grapefruit juice in the simple syrup.
You will have some leftover grapefruit simple syrup that may be reserved for a different use (like iced tea or a cocktail or more popsicles!). It's just hard to make a batch of simple syrup that's less than ¼ cup. I make the simple syrup in my tiniest pot, which is a stainless steel ⅝-quart butter warmer.
As tempting as it is, don't increase the vodka in this recipe or your popsicles will remain slushy and never freeze solid.
This recipe yields 18 ounces of liquid to be divided between six 3-ounce popsicles. You can use a measuring cup filled with water to determine the capacity of one popsicle in your popsicle mold, then adjust this recipe accordingly.
