Let's get into some history. Capsaicin was first extracted in 1816 by Christian Fridrich. Further work by John Clough Thresh led to its naming in 1876, but it wasn´t until 1898 that Karl Micko isolated the compound in pure crystalline form. A century later, in 1997, David Julius discovered and cloned the cellular receptor for capsaicin, and brought a new level of understanding on how capsaicin works. We´ll get more into this science in the second part of this blog.

First, I should say that recipes for Chiu Chow chili sauce are rather limited. A quick Google search rendered relatively few findings—just a handful of variations that left me less than satisfied. So, I turned to a key source in any home cook’s arsenal—the label on the store-bought version.

First off, capsaicin affects every animal species besides birds. These feathered friends don't experience the pain caused by capsaicin, which makes them the plants´ greatest ally in carrying seeds over long distances. This is a great example of evolution; it just makes sense to produce a compound that repels potential predators but does not affect your greatest seed carriers.
