HANDY HINT. Parmesan cheese! Keep the rind of your parmesan cheese (the hard end) in your freezer, stir through soups and sauces to boost the flavour of your favourite meals! You can even add rind to olive oil for a parmesan infused oil! (Delish!) Shredded parmesan cheese can be frozen for up to 2 months. Enjoy, The DT Team x
