A single bite of a Donsuemor Lemon Madeleine will send you spiraling into a Proustian reverie, a temporal trip back through faded memories of seaside holidays in Balbec, of the plangent pangs of first love, of the forbidden frisson of espying two aristocrats engaged in the love that dare not speak its name.

Well, maybe. More likely, you’ll simply be overwhelmed with the savory flavors of these crumbling, lightly lemony snacks. Of course, it was a nibble of a sweet, shell-shaped cookie like this that famously flooded Marcel Proust with sense memories of bygone days, which he then wove into his mammoth, exquisitely florid seven-volume mytho-memoir, Remembrance of Things Past (more accurately, à la recherche du temps perdu, or In Search of Lost Time). Proust may have been overwhelmed by no more than a morsel, but we defy you to keep from scarfing the whole bag.

Yes, chances are these indulgent, citrusy snacks — new variations on DonSueMor’s traditional and chocolate-dipped varieties — won’t impel you to craft one of literature’s most sweeping and elaborate works. But whatever your writerly inclinations, this is one petit gâteau you won’t soon forget.
