Do not boil simple syrup for more than the time it takes to dissolve. It you overcook your syrup it will eventually become caramel.If you want to make a larger batch use the ratio 1:1 for the sugar and water.If you want to use peppermint candy (like candy canes) instead of extract simply add 1/4 cup candy pieces to the mixture after dissolving the sugar. Let simmer for 2-3 full minutes. Then allow the syrup to cool in the pan. Remove the candy pieces before storing the syrup.If you want to use fresh peppermint instead of extract simply add 5-6 leaves to the mixture after dissolving the sugar. Let simmer for 2 full minutes. Then allow the syrup to cool in the pan. Remove the mint pieces before storing the syrup.
