Method
- Wash the apple, remove its core and seeds, and dice the flesh. Put the water and sugar in a small saucepan over medium-low heat. Stir until the sugar dissolves, then add the apple pieces.
- Bring the mixture to a gentle simmer. Lower the heat, partly cover and cook for about 10–12 minutes, stirring occasionally, until the apple softens. Keep some liquid in the pan and avoid boiling it down to a sticky glaze. Cooking times depend on the apple and pan.
- Set a fine-mesh sieve over a heatproof jug. Carefully pour in the mixture and let it drain for about 5 minutes without pressing the apple. Leave the syrup to cool for about 10 minutes, using a shallow heatproof container if needed. Measure the yield. Reserve 1/4 cup for the four drinks and refrigerate the rest promptly.
- For each drink, stir 1 tablespoon of cooled apple syrup and 1 teaspoon of caramel syrup into 3/4 cup of chilled coffee. Add about 3/4 cup of ice to a tall glass and pour in the flavored coffee. Taste before adding more syrup. If using oat milk, add up to 1/4 cup and stir. Repeat for the other glasses and serve immediately.
Notes
Recipe development note: This formulation has not been kitchen-tested. Preparation times are estimates; follow the texture checks and product instructions.
The recipe makes four drinks using coffee that is already brewed and chilled. The apple syrup should yield roughly 1/2 cup, but evaporation and straining will change the amount. Four drinks use 1/4 cup of syrup altogether; refrigerate any remainder. Cooling the brewed coffee is not included in the stated recipe time.
Start with the measured amounts rather than pouring both syrups freely. Caramel can quickly cover the apple flavor. If that happens, use less caramel in the next glass; adding more apple syrup to an already sweet drink may only make it sweeter.
Pressing the apple through the sieve makes a sauce-like mixture with pulp. Let gravity do the draining for a cleaner drink. Some cloudiness is still possible with fruit syrup. If the chilled syrup is too thick, thin the portion you are using with a teaspoon of water, rather than reheating the whole jar.
Refrigerate unused apple syrup promptly in a clean covered jar at 40°F/4°C or below and use it within four days as a conservative household limit; its shelf life has not been tested. This formulation is not suitable for shelf-stable storage or home canning. Use a clean spoon each time. Assemble the coffee over ice only when serving, and keep any added milk refrigerated. Perishable drinks should not sit out beyond two hours, or one hour above 90°F/32°C.
