Preparation, uses, and tips

In the spring, when sorrel’s rather sour flavour is mildest, it is used in salads and cooked as a vegetable. A few slivered young sorrel leaves add a refreshing touch to any sandwich. The fresh young leaves can be combined with other herbs in salads, or cooked and served like spinach, usually in combination with either Swiss chard or spinach. When more mature and acidic, sorrel is used to flavour cream soups; it’s also pureed as an accompaniment for meats and vegetables, and used in omelets and breads.

To puree sorrel, wash the leaves and pull off the stems. Then lay about two dozen leaves parallel in a neat pile, roll into a fat cigar, and shred the leaves crosswise with a knife. Place these shreds in a pan with a generous teaspoon (5g) of butter—or a little water, olive oil, or cream—for each quarter pound of leaves. Over low heat with occasional stirring, the leaves will melt into an olive green puree in about 15 minutes. The puree can be strained to remove any leaves, if you like.

Cream of sorrel soup is a famous Old World dish, and salmon with sorrel sauce is a popular dish in France.

Due to its high acid content, sorrel can cause a reaction in some metals. When cut, it will discolor a carbon steel knife, as well as aluminium or iron cooking pots and silver serving dishes.
