I think my summer mood spike has more to do with all the fresh produce and increased vitamin intake than the extra sunlight. I’ve been particularly obsessed with nectarines and arugula. With arugula, it matters what kind you buy: the brand shown below has sharp, peppery leaves, while the organic Kroger brand shown here has larger, less textured leaves and a mild flavor. Both have their uses, although I prefer mine with a little more bite.
