Without coffee he could not work, or at least he could not have worked in the way he did. In addition to paper and pens he took with him everywhere as an indispensable article of equipment the coffee-machine, which was no less important to him than his little table or his white robe. He allowed nobody else to prepare his coffee, since nobody else would have prepared the stimulating poison in such strength and blackness. And just as in a sort of superstitious fetishism he would use only a particular kind of paper and a certain type of pen, so he mixed his coffee according to a special recipe, which has been recorded by one of his friends: “This coffee was composed of three different varieties of bean — Bourbon, Martinique, and Mocha. He bought the Bourbon in the rue de Montblanc, the Martinique in the rue des Vieilles Audriettes, and the Mocha in the Fauborg Saint-Germain from a dealer in the rue de l’Université, whose name I have forgotten though I repeatedly accompanied Balzac on his shopping expeditions. Each time it involved half-a-day’s journey right across Paris, but to Balzac good coffee was worth the trouble.”
