>>24071405Chili oil is great for adding heat, the oil isn't washed away so easily in your mouth so the heat lasts a little longer. I like MSG anyways and have a jar that I add to tacos, mac & cheese, baked chicken and more. Sometimes it says 'MSG' right on the package, sometimes it's called 'Umami Flavoring'. It's a salt that lasts forever and is usually pretty cheap so it's not a gamble to buy and try adding to different things.
