Pancake mix in particular benefits from the large scales at which the pre-mixed stuff is made. Measuring out those smaller proportions of dry powders precisely and accurately is much more difficult at home even if you opt for using a scale instead of measuring cups. Just read the ingredients list to avoid the brands that may include the extra binders and other ingredients you want to avoid.
No. No. No. Don’t just buy a raw one if you don’t know what to do with it. Find a place that has prepared it in something. I recommend durian ice cream. The waitress warned me that it tasted like gas. I asked her if she meant the fuel or farts and she just repeated “gassy”. It smelled sweet like unburned gasoline at a classic car show and earthy like a belt loosening fart. And yet somehow it doesn’t actually taste bad. It’s mostly just unsettling that it tastes as good as it does. I’m not sure I’d order it again, except on a dare or to horrify any companions that haven’t experienced it yet. It’s like spicy food, sometimes you’ve got to power through the initial stink/spice to really get to the hidden flavors.
