All this time I KNEW there is an off taste, but so many don't notice (OR are in denial ;<

THANKS to all! Interesting about onions, garlic. My objection is more prevalent w/red meat dishes, and theorize it has to do with no fond, AND no fat rendered off in slow cooker... My taste id's the off part as cloying and lacking in depth, missing acidity. Haven't owned a slow cooker in 25 years; when with a meal, I add lemon or vinegar or a sauce, like Heinz 57 to "cover" that off part. Helps, but usually not enough.
