A formula is the alpha and omega of every perfume--skull cufflinks

During the rather lengthy interruption that had burst from him, Grenouille had almost unfolded his body, had in fact been so excited for the moment that he had flailed both arms in circles to suggest the "all, all of them" that he knew. But at Baldini's reply he collapsed back into himself, like a black toad lurking there motionless on the threshold.
"I have, of course, been aware," Baldini continued, "for some time now that Amor and Psyche consisted of storax, attar of roses, and cloves, plus bergamot and extract of rosemary et cetera. All that is needed to find that out is, as I said, a passably fine nose, and it may well be that God has given you a passably fine nose, as He has many, many other people as well- particularly at your age. A perfumer, however"-and here Baldini raised his index finger and puffed out his chest-"a perfumer, however, needs more than a passably fine nose. He needs an incorruptible, hardworking organ that has been trained to smell for many decades, enabling him to decipher even the most complicated odors by composition and proportion, as well as to create new, unknown mixtures of scent. Such a nose"-and here he tapped his with his finger-"is not something one has, young man! It is something one acquires, by perseverance and diligence. Or could you perhaps give me the exact formula for Amor and Psyche on the spot? Well? Could you?"
Grenouille did not answer.
"Could you perhaps give me a rough guess?" Baldini said, bending forward a bit to get a better look at the toad at his door. "Just a rough one, an estimation? Well, speak up, best nose in Paris!"
But Grenouille was silent.
"You see?" said Baldini, equally both satisfied and disappointed; and he straightened up. "You can't do it. Of course you can't. You're one of those people who know whether there is chervil or parsley in the soup at mealtime. That's fine, there's something to be said for that. But that doesn't make you a cook, not by a long shot. Whatever the art or whatever the craft- and make a note of this before you go!-talent means next to nothing, while experience, acquired in humility and with hard work, means everything."
He was reaching for the candlestick on the table, when from the doorway came Grenouille's pinched snarl: "I don't know what a formula is, maitre. I don't know that, but otherwise I know everything!"
"A formula is the alpha and omega of every perfume," replied Baldini sternly, for he wanted to end this conversation-now. "It contains scrupulously exact instructions for the proportions needed to mix individual ingredients so that the result is the unmistakable scent one desires. That is a formula. It is the recipe-if that is a word you understand better."
