Nic Roome’s madeleines have become my latest edible obsession. As far as I can gather, he runs a small operation out of his house and is a recent convert to the world of artisan food production, having left a career at Burberry to pursue baking. I was first introduced to Roome’s madeleines by my friend Kitty Travers, my official London food guru, at Monmouth Coffee’s Bermondsey location. Since it is only open on Saturdays, I sort of panicked at the thought of having limited access to these golden scallops of ground almond and lemon zest cake. I later found that these morsels are available at Monmouth Coffee’s Covent Garden and Borough Market shops, though only on Thursdays. For now, Roome’s madeleines are far too scarce for comfort, but they sure are worth the wait.
