This isn't actually Spinach; it's Perpetual Spinach, which is a type of Chard. Even so I always refer to it as Spinach, and I grow lots.
Unlike the 'real thing', this gorgeous leafy vegetable has a substantial consistency somewhere between real Spinach and Swiss Chard. One still requires quite a large picking for a meal.
For me it has three great virtues. It is very good for you, it tastes wonderful, and (best of all) it is rather like eating green vegetable SILK.
I wash, take off the longer stems, and steam for about 8 mins.The perfect accompaniment for a simple Pork chop. What could be easier!
