Once when I was frying garlic, there arose a strong stench of ... no, it couldn’t be ... tree frog piss! It had taken me a million years to just peel a few garlic cloves, and I wasn’t about to spend my remaining life peeling more. So I added extra spices to mask the odour. I can’t be sure if the compliments that followed were the result of my expert cooking or that undercurrent of, shall we say, the chef’s secret ingredient.
