Add 1 tablespoon of lye to 1 pint of water. It will give off vapor, so do this in a well ventilated area and don't breathe it. Likewise, use chemical resistant, or at least nitrile gloves to keep it off the skin. Swab or brush the mixture onto the cherry, and it will react with the tannic acid in the wood. Keep applying until you get the desired color, but it will be lighter when dry. Rinse with water if you're satisfied, or just leave it dry.
Lye is base, so neutralized with an acid like vinegar. You don't need to neutralize the lye on the stock, rinsing with water at most, but the vinegar might be handy if you get splashed.
Unlike stain, this method adds no pigment to muddy the grain. Finish with tung oil, BLO, or whatever varnish you like.
