How about I give you something that looks appropriate and tastes good too? Here's an oldie-but-goodie from the 1930 Savoy Cocktail Book:
Albemarle FizzThere you go. It's a modified gin sour, but with the added benefit of a little fizz, and the lovely, somewhat bloody look of the more dense raspberry syrup settling in the bottom of the glass. Tip tip hurrah, boils and ghouls!
juice of 1/2 lemon (about 3/4 oz or so)
1/4 oz simple syrup
1 1/2 oz gin
2 bar spoons raspberry syrup
Shake lemon juice, syrup and gin with ice, strain into glass. Top with seltzer and add two bar spoons raspberry syrup.
