I have several jams, a couple shrubs, some syrups and dried herbs that all wanted to be used in a drink this month but I decided to go with raspberry syrup. It's a classic cocktail ingredient that is rarely used these days. The traditional way to make it would be to make a simple syrup and put some raspberries in it, wait a couple days and then strain the fruit out. My parents have a big raspberry patch and they make jelly every year. My dad gave me some jelly that didn't set up properly. The pectin didn't work and it never jelled. So it is syrup. Useless for toast but perfect for cocktails. It is made from sugar, raspberry juice and (worthless) pectin.
2 1/2 oz Rye whiskey
1/4 oz Benedictine
2 barspoons Raspberry syrup
2 dashes Angostura bitters
1 dash Orange bitters
Stir with ice and strain into an old fashioned glass with a large rock.
Adjust to taste depending on the sweetness and the raspberriness of your syrup.
I really like this one. The rye gives it some weight and some spice, the benedictine brings some sweet herbal notes, the syrup brings a fruity sweetness and the bitters bring the bitter complexity. I've made it using less raspberry syrup and a little simple syrup but I cant decide which way I prefer it. Even with 2 barspoons of my raspberry syrup it isn't too sweet nor overwhelmingly fruity. The photo looks much more red than the real thing because it was backlit by a beautiful day.
