Once you have finished making your shatta, you should store it in your fridge. It will keep in the fridge for several months, but I like to use it up within 1 month. The olive oil may solidify, and that’s completely normal. Leave the jar on the counter for 30 minutes before using it and the oil should liquefy again. Shatta can be frozen in ice cube trays and transferred to a freezer bag for longer-term storage.
