To freeze uncooked churros, place the piped churro batter on a baking tray lined with wax or parchment paper.
Make sure to leave at least 1cm of space between each churro (you don’t want them touching) and cover the baking tray with plastic wrap to prevent any freezer burn.
Leave the churros to harden in the freezer for roughly one hour, or until they feel hard to the touch.
Once they’ve hardened sufficiently, transfer them to an airtight container. Since they’re already frozen, they won’t stick together.
