HELP! My darling husband has started dinner for us, but upon tasting the tomato sauce for our lasagne, it seems the garlic was off! It tastes like damp, wet, mildew, blah! Is there anything I can do to fix this? I have tried adding a little sugar, but it hasn't made much difference. DH is willing to throw it, but I'm hoping it can be salvaged! Thanks
Unless your garlic has fungus growing on it or is badly discolored it's unlikely this flavor is from it. Garlic generally keeps very well and is still safe to use, and still flavorful even when it's a bit shriveled.
It's much more likely these off flavors are coming from another ingredient, and could be a sign of some sort of contamination, in which case you should chuck it. Even if it isn't you can't get rid of the flavor, so my recommendation should be to get rid of it and order some take-out.
No, you cannot salvage it.
First, once a flavor is in a dish, there is no way to remove it. Masking it slightly (which diverts the attention from it but does not remove it) and dilution are possibilities, but removal isn't.
Second, mildew is mold, and many species of mold are toxic to humans. As there is no way to find out if yours is toxic or harmless, eating it puts you at risk of landing in the hospital with something unpleasant - certainly not worth risking over a 10 bucks pot of stew.
