And cornichons with pearl onions? In reality, there is nothing fancy about cornichons despite their Gallic pedigree. Pearl onions are the guest stars, adding another layer of taste and texture. Sharing my enthusiasm, my colleague Lauren says that cornichon and pearl onion sprinkled atop a liberally buttered slice of toast is one of her all-time favorite drunk meals. Many days a jar of cornichons is what makes my cobbled-together meals feel complete.
