A thread on sustainable aquaculture led me to another excellent lecture: the same chef shares the best culinary experience of his life. A farm that is so good for geese, wild ones stop their migration and join the farm population; instead of force feeding, Eduardo Sousa makes sure there are enough figs, olives, and lupine seeds around that the geese eat more than their confined counterparts.
The lupine was important, because it gives the
foie gras the bright yellow color chefs have been schooled to look for; actually, a brighter color, because yellow lupine produces a stronger pigment than commodity corn. With that development, he won first prize in the authoritative worldwide competition for the stuff.
I strongly recommend the video, if bandwidth allows.
