" Working with chocolate always helps me find the calm centre of my life. It has been with me for so long; nothing here can surprise me. This afternoon I am making pralines, and the little pan of chocolate is almost ready on the burner.
I like to make these pralines by hand. I use a ceramic container over a shallow copper pan: an unwieldy, old-fashioned method, perhaps, but the beans demand special treatment. They have traveled far, and deserve the whole of my attention. Today I am using couverture made from the Criollo bean: its taste is subtle, deceptive; more complex than the stronger flavors of the Forastero; less unpredictable than the hybrid Trinitario. Most of my customers will not know that I am using this rarest of cacao beans; but I prefer it, even though it may be more expensive. The tree is susceptible to disease: the yield is disappointingly low; but the species dates back to the time of the Aztecs, the Olmecs, the Maya. The hybrid Trinitario has all but wiped it out, and yet there are still some suppliers who deal in the ancient currency.
Nowadays I can usually tell where a bean was grown, as well as its species. These come from South America, from a small, organic farm. But for all my skill, I have never seen a flower from the Theobroma cacao tree, which only blooms for a single day, like something in a fairytale. I have seen photographs, of course. In them, the cacao blossom looks something like a passionflower: five-petaled and waxy, but small, like a tomato plant, and without that green and urgent scent. Cacao blossoms are scentless; keeping their spirit inside a pod roughly the shape of a human heart. Today I can feel that heart beating: a quickening inside the copper pan that will soon release a secret.
Half a degree more of heat, and the chocolate will be ready. A filter of steam rises palely from the glossy surface. Half a degree, and the chocolate will be at its most tender and pliant. "
