Interesting, as i pair all my cigars with cheap coffee with heavy cream and sugar, yet only once since I started paring with anything just to clear my palate every so often, have i noticed a sweet taste to a cigar, and I'm sure it was unrelated to the coffee.
I have noticed that eating anything spicy will give a false spiciness to a cigar though, so wait until the spice has completely dissipated before smoking.
I friggin love cigars
