Courgette and marrow au gratin

Courgette, also called zucchini and marrow grow on the same plant but the marrow has been left on the plant longer.

Marrows are waterier in texture and less tasty than the younger, sweeter courgettes. As with courgettes they are equally great to stuff, can counter spicy food, or be served as a side dish or as vegetable spaghetti. 

Today’s recipe is easy and combines both courgette and marrow thinly sliced which creates a nice colour and pattern. You’ll see that food is not only about flavour and the way a dish is presented is as important.
