I love sorrel in smoothies. If you’re not familiar with sorrel, it’s a leafy green with a distinctly tart lemony flavor. Unlike many greens (ahem… kale…) that have flavors and textures that require many additional ingredients to make a tasty drink, sorrel shines with little encouragement and is wonderfully refreshing on a hot afternoon. (I may be sipping at one as I type.) You’ll also find that sorrel is very high in vitamins A and C, and is a good source of many B vitamins, potassium, and manganese. Please note that people who are prone to kidney stones need to be careful with sorrel as it does contain oxalic acid.
