I conducted training at a company that provides oil for different restaurants once. Kind of in an offhand manner they told us they add a little silicone to the oil to keep it from emulsifying during transit. My face 😳 I already know all about bad oils and fats, and after that job, I won’t eat anything from a restaurant. You don’t know what they cook that food in and you don’t know what’s in those condiments that you’re buying.
