Yes. you can. Infusions without sous vide are possible but take much longer. Most liquor infusions will take anywhere from 24-48 hours or 3-5 days depending on the flavors. If using nonperishable ingredients (such as dried herbs) you can infuse them at room temperature. If using perishable goods (such as fresh fruits) then store them in the fridge during the infusion process. For this recipe, place everything in a mason jar and store it in the fridge for 3 days. Strain and enjoy!
