Is this Ruth Bourdain?

Ash, although not cigarette ash, can be used in making cheese. Not coleslaw however.

I hope you are kidding.

I once had a particulalry awful dessert at at restaurant in Barcelona- the whipped cream was flavored to taste like a cigar ash....really vile.
Toss it.

We're enjoying your "unusual" cooking dramas, and subtle sense of humor. Looking forward to helping you with a real question someday soon.

Really bad. Don't do it. Please.

That might be gross. Wood ash is used in nixtamal (processed corn) but only as a way to break down protein, then it's washed away. Tobacco ash + cigarette additives won't taste good in food. No judgement, but if you smoke while cooking, doesn't it make all your food taste like cigarettes?
