Infusions
In a small skillet over medium-low heat, toast the sesame seeds, stirring often, until fragrant and slightly golden, about 4 minutes. Let cool slightly. Place the sesame seeds and rum in a bowl and stir to combine. Let stand at room temperature for 5 minutes. Strain through a fine-mesh sieve lined with several layers of cheesecloth, then funnel back into the rum bottle and refrigerate until ready to use, up to 3 months.
