When cleaning the Swiss chard we advise you to strip the green leafy portion from the harder white stalks. Add the stalks to the boiling water first, and then after a few minutes the leaves. In this way you will get a more evenly cooked result.
Trivia
Swiss chard provides significant amount of vitamins, in particular the pro-vitamin A, iron and magnesium. It is therefore excellent for health, particularly that of children.
