I returned to the Jay Steve Value Oven in the backyard. In my absence, the Cabrillo Street cats had made it into their lair. I shooed them away and built a fire. Cornelia came outside and watched me learn to bake again for the first time. Mainly, we sat in companionable silence. Then, one morning, after we’d pulled a couple of particularly plump loaves from the Jay Steve, I told her I was leaving.
“A lot of people have lived in that apartment,” she said, “but none of them ever fed me before you came along.”
I told her I’d leave her some of the starter so she could bake her own bread.
She narrowed her eyes. “What am I getting myself into? Is it high-maintenance? I don’t like high-maintenance.”
“Not this one,” I said. “It’s boring.”
THERE’S A CRATE HERE at the restaurant in Kreuzberg. It’s enormous, and it’s addressed to NUMBER ONE EATER. Is it a mistake? Are you inside the crate? I banged on it and called your name, but there was no reply. Then I pried it open (sorry), but there was just another box inside. This one is bright blue, with a lightning bolt.
Lois, what’s going on?
BEO! Inside that big blue box there is a refurbished Vitruvian 3 robot arm, partially disassembled, loaded with software I helped create. That robot and I have been through a lot together. I have things to teach it still.
I’m coming to Berlin.
I’m starting a new business, and I need your help. I want to learn how to use knives correctly, and which vegetables are which, and how to make my own spicy soup. (That’s not a euphemism.) (It could be a euphemism.) If you can teach me, I can teach the Vitruvian, and then those skills can be shared in a new way, thanks to my former employer. The world is going to change, I think—slowly at first, then faster than anyone expects. It’s going to be a weird time, but along the way I think I can get rich. We can get rich.
Beo, I’ll bring plenty of Fresno chilies.
I also want to learn how to bake sourdough the way you did on Clement Street. Honestly, mine was never as good. But I have one condition, and you might not like it.
Let’s not use the starter of the Mazg.
It almost caught me, Beo. And then it caught someone else. It starts out very sweetly, doesn’t it? The songs, the smiles. One night, I saw a dusting of pinprick lights. Luminous powdered sugar. That feels like a long time ago. Maybe, if you’re lucky (or if you’re you), the starter of the Mazg stays sweet. But if you’re not, it sneaks up on you—the ambition, the impatience, the hunger … I’ll tell you the whole story when I get to Berlin. There aren’t any pirates in this one, but it does feature a great rocky island, along with some very heroic goats.
This time, I’m bringing you a starter: authentic San Francisco sourdough, native citizen of Cabrillo Street. I captured it myself. I will decant it into a plastic container small enough to take through airport security. If challenged, I will claim it’s moisturizer.
In Berlin, it will grow.
It will make no faces and sing no songs, but I guarantee you, it will do its part. And, Beo, working there with you, I will set myself, at last, to the task of learning mine.
