If your schnapps or vodka infusion is too weak-flavoured you can enhance the flavours by adding a little, little bit of sugar.
Sugar is a great flavour enhancer.
You can add the sugar directly, but because sugar is more soluble in water than in alcohol, it's usually better to make a simple sugar syrup and add it to your infusion little by little.
Never use artificial sweeteners - NEVER! You will ruin the taste.
Sugar syrup recipe
Ingredients
1 part white, granulated sugar
2 parts water
A little lemon juice
Direction
Combine sugar and water in a saucepan.
Cover it and slowly heat over medium heat.
Stir occasionally.
Let it simmer for 20-30 minutes until the sugar is completely dissolved.
Do NOT boil.
Add a little lemon juice to prevent crystallization.
Let the sugar syrup cool to room temperature.
Add the sugar syrup to your infusion. Little by little, until it suits your taste.
Leave the infusion for a couple of days to settle - in a dark place at room temperature.
Then taste it again, it might need some more sugar syrup.
