Oliver Ryan's sister-in-law starts a blog about her intensive course at the French Culinary Institute:

"But I will share a little lesson in agriculture. According to the University of California Agricultural Extension, it takes about 23 gallons of water to produce a pound of potatoes. And so it could be argued that with each potato we slice apart into little Cocotte morsels, we are sacrificing almost six gallons of water. That’s almost three flushes on the water-saving toilet we just had installed. The toilet that, ehem, only gets flushed when absolutely necessary."
