01 - Combine cherry preserves, water, and lemon juice in a small saucepan. Heat over low heat, stirring constantly until smooth and syrupy, approximately 2 minutes. Strain through a fine-mesh sieve if a smoother texture is preferred.
02 - Extract one shot of espresso using an espresso machine or brew 1/4 cup of strong coffee using a coffee maker or French press.
03 - Heat milk in a small saucepan until steaming, then froth using a steam wand, handheld frother, or whisk until foamy. Alternatively, use a milk frother for optimal texture.
04 - Add prepared cherry syrup and vanilla extract to a large mug. Pour hot espresso over the syrup mixture and stir thoroughly to incorporate flavors.
05 - Pour steamed milk over the espresso-cherry base, holding back foam with a spoon. Gently spoon remaining foam onto the surface of the latte.
06 - Top with whipped cream, drizzle additional cherry syrup, and garnish with a fresh or maraschino cherry. Serve immediately while hot.
