Start by zesting approximately three oranges, ensuring you only capture the vibrant orange skin without the bitter white pith. In a medium bowl, combine the fresh orange zest with granulated sugar. Using your fingers, rub the mixture together for about 2-3 minutes until it resembles wet sand and releases a delightful citrus aroma.

Transfer the zest-sugar mixture into a saucepan. Squeeze the zested oranges to obtain freshly squeezed orange juice, ensuring you have enough liquid to combine with the sugar. Pour the juice into the saucepan, mixing it well with the sugar mixture.

Place the saucepan over medium heat and bring the mixture to a gentle simmer, stirring continuously for about 3-5 minutes. Watch as the sugar gradually dissolves, and the syrup begins to thicken slightly.

Once the sugar has fully dissolved and the syrup has simmered, remove the saucepan from heat. Strain the mixture through a fine mesh sieve into a heat-resistant bowl or jar to eliminate any zest or pulp.

Allow your homemade orange simple syrup to cool at room temperature for about 10-15 minutes. Transfer the syrup into an airtight glass jar or bottle. Seal it tightly and store it in the refrigerator for up to two weeks.
