You can enjoy the ice cream right away (as soft serve) or place in a container and put in the freezer if you prefer a firmer result. If you don’t have an ice cream maker, place in an airtight container in the freezer, and stir (with a whisk or hand blender) every 30 minutes until set. You will get a slightly different texture but the taste will still be great. Recipe modified from Max Falkowitz' Serious Eats (seriouseats.com).
