AIMEE BLUME: Saucy sorrel enlivens salads Sorrel (Rumex acetosa) is an early-growing spring herb suitable for salads or seasoning. It is a very tart herb, full of sour oxalic acid, the chemical which also gives rhubarb its sourness (as well as the annoying yellow-flowered shamrock-shaped oxalis weed that springs up in your garden all summer).
