Harvard SEAS lecture, 11/26/12, David Chang and Carles Tejedor

The lecture was split into three parts: Professor David Weitz gave the science opening and explained why, even though oil+water is opaque, Carles Tejedor’s olive oil gelee is clear. (The opacity is due to the mismatch of index of refraction between oil and water. Water has a lower index of refraction than oil. The sugar in the olive oil gelee increases the index of refraction of water almost to that of oil.)

The second part of the lecture was a short food demo by Carles Tejedor in which he plated oil yogurt (made up of 25% extra virgin olive oil, the yogurt was made pretty via spherification) and some olive oil bread (made up of 50% olive oil, I think he said).

The third and longest part of the lecture was David Chang waxing poetic about microbes. (^_^)
It really wasn’t anything that he hasn’t talked about before, so I won’t bother rehashing it. Just enjoy the pictures below.

As for audience goodies, we got to try the olive oil yogurt with olive oil breadcrumbs. We also got about 1/2 tsp of cashew miso, and three vials of mystery liquid. The first vial was cashew tare (the fermented cashew juice that separates out post-centrifuging). The second was olive “soy sauce, which tasted like salty concentrated olive juice. And the last vial was fermented olive juice which was very bitter to due oleuropein, a chemical compound which naturally occurs in olive.
