A nonalcoholic spritzer made with a Honeycrisp apple concentrate (you could make the concentrate with any apple juice that you like) and sparkling water, with no added sugar!
Pour the apple juice into a large pot. If you don't have a pot large enough, make the concentrate in two batches. Bring the juice to a boil over medium-high heat on the stove, then reduce the heat to maintain a simmer. Continue to simmer until the juice has reduced to about 3 1/2 cups. Remove the pot from the heat and let the concentrate cool slightly before pouring into a glass quart jar. Let the concentrate continue to cool until it is warm, then put the lid on the jar and refrigerate the concentrate until it has chilled before using. The concentrate will keep in the refrigerator for several weeks.
For each sparkler, pour 2 ounces of the Honeycrisp Apple Concentrate into a glass, then top off the glass with sparkling water. Garnish with an apple slice, if desired. Enjoy immediately.
