Tip: Don’t drop your courgettes! If not bruised, the hard skin of a large courgette helps to retain moisture in the flesh.
When refrigerating, store in a vegetable storage bag in the crisper/fruit compartment. Otherwise, you can store in a cool place away from direct heat and use sections at a time. Remember to peel off the skin and remove the pith/seeds if they’ve gotten too large.
