Toast your almonds in a 400° oven. Spread them evenly in a pan or baking dish with sides.
Once removed from the oven, use a blender or food processor to pulverize the almonds.
In your saucepan on the stove, combine your sugar and water to make a simple syrup. Make sure it doesn't boil, so you can combine your ingredients and then turn up the heat to about medium.
When your syrup is clear and just about to start boiling, add your pulverized almonds to the saucepan.
Stir things around a bit, and as your mixture comes to barely a boil, cover it and remove from the heat.
Let your almond syrup chill for a minimum of 3 hours, maximum of 12 hours.
Strain into a bowl or other container with a cheesecloth. Fold it so there are at least 3 layers or so.
Strain in small batches and discard your sugary almond bits.
Once your strained concoction is complete, add your rose or orange water and vodka.
Funnel into a storage container, and pop it in the fridge! This should last you about a month in the fridge.
