A simple syrup recipe consists of two basic ingredients: equal parts sugar and water. To make it, combine 1 cup of water and 1 cup of granulated sugar in a pot, then simmer over medium-high heat while stirring occasionally until the sugar dissolves completely. Remove from heat and let it cool before storing in an airtight container in the refrigerator for up to four weeks. Optional flavor variations can include adding herbs like rosemary, mint, or lavender, or citrus peels such as orange or lemon during the cooling stage for infused syrup. This syrup is commonly used to sweeten cocktails, coffee, tea, and various desserts.
