  • Leftover Passata

    Hi Nigella, I have leftover passta after making your Calabrian Lasagne. Can I can I freeze it? Hate wasting it! Thanks!

    From the nigella team:

    Passata is made from pureed tomatoes, which are usually then sieved or strained to give a smooth, slightly thickened tomato liquid. In the UK and Europe it is usually easy to find, in the US tomato sauce is a good substitute. It is usually sold in a jar, can or carton.

    It is possible to freeze leftover passata, however you should do so as quickly as possible, and within 24 hours of opening (once opened any unused passata should be immediately transferred to the frdge in an appropriate container). The passata must be removed from its original packaging and transferred to an airtight container before freezing. The passata can be frozen for up to 3 months and should be thawed overnight in the fridge before using. We would also suggest that any frozen passata is used up within 24 hours of thawing. 

    It is also possible to freeze the leftover passata in ice cube trays. Once frozen, transfer the cubes to a resealable bag. Again it will keep for 3 months and should be thawed before using. This can be useful if you feel that you may only the passtata up in small quantities as you can then just remove the number of cubes you will need.
