Toast almonds at 400°F (200°C) for 4 minutes, shaking after 2 minutes.
Cool almonds and then pulverize them with a blender or food processor.
In a saucepan, cook sugar and water on medium heat until sugar dissolves and the mixture starts to boil, about 3 minutes, stirring constantly.
Add pulverized almonds and simmer on low heat, stirring frequently. When mixture is about to boil, remove from heat and cover. Let it sit for a minimum of 3 hours and no more than 12 hours.
Strain steeped mixture through 3 layers of cheesecloth into a bowl, squeezing the cloth as you go.
Add orange flower water and vodka, then stir. Funnel into a glass jar or bottle.
