Combine jam, water, and vanilla in a medium saucepan and heat over medium heat until bubbles just begin to form. Stir and cook for about 2 minutes, then remove from heat. Allow mixture to cool for 5-6 minutes, then pour through a fine mesh strainer into an air-tight jar or bottle. Once the mixture is cool, you're ready to start making cocktails!
Store in the refrigerator for up to 2 weeks.
Pro tip: Have an empty Raven's Nest jam jar? Repurpose your jar to store your simple syrup!
Coat the rim of an old-fashioned glass with a touch of lemon juice then dip in sugar. Combine simple syrup and gin. Top with ice and a splash of club soda to taste. Garnish with fresh pears and enjoy!
