Take equal parts sugar and water (I usually use 1 cup of each) and add in the hardier flavorings like citrus rind, rosemary, black pepper, cinnamon sticks. Bring to a boil, let the sugar dissolve, and boil for one minute. Take off of the heat, and add in the softer fruits, like raspberries, peaches, cherries. I usually add about ½ cup of fruit, though more or less will not be that big of a deal. Let steep for 20 minutes and strain out the solids. The syrup will keep in the fridge for a few weeks (if it lasts that long).
