In a small saucepan over medium-high heat, mix together the raspberries, Dixie Crystals sugar, and water. Bring to a high simmer. Stir and let cook for about 5 minutes when the mixture turns a deep red. Take off the heat and let stand for 15 minutes.

Place a fine-mesh sieve or strainer over a bowl and strain the raspberry mixture. Gently press the mixture to strain all the liquid. Discard the solids and seeds. Set aside and let cool. Pour into a clean jar and store in the refrigerator.

Once the syrup has cooled, take a food-safe plastic syringe, and fill the syringe to about 1/2 to 3/4 ounce.

In a cocktail shaker filled with ice, add the gin and lemon juice and give it a few shakes. Strain into a highball glass filled with ice. Top off with club soda. Place the “blood-filled” syringe in the glass and serve.
