Reddit reviews Living Nutritionals All-Natural Pure Liquid Smoke 5oz (147ml)

Liquid smoke is a pretty important ingredient when you're trying to simulate a meat taste. It's what gives bacon it's flavor so it's a great way to fool the senses. If Amazon delivers in your area, you can order from them. https://www.amazon.com/gp/product/B00R3SUZDO/

Liquid smoke flavor has a pretty huge variance, plus its expensive, and you'll feel kinda bad when you have to throw it out cause its gross. I use this, I wouldn't call it bitter, but I would call it strong as all hell (1/2 tsp max in something large).
