Adapted from Margaret Grade by Chelsea of the By The Seasons blog.Margaret Grade, of Manka’sInverness Lodge in California, brought this twist on German potato salad to a ChezPanisse reunion picnic. (Just imagine going to a potluck with Alice Waters andDeborah Madison!) The richness of the bacon is balanced by the purslane’sacidity, and the resulting salad is quite delicious with a satisfying texturethat will have guests reaching for seconds.
