1 English style cucumber, sliced
  2 Tablespoons French's mustard
1/2 teaspoon Galangal (Laos)
1/2 teaspoon Ginger
  2 Tablespoons sugar
  5 Tablespoons Balsamic vinegar
1/8 teaspoon Tarragon
1/8 teaspoon Garlic


Put the sugar in a bowl. I recommend to keep the sugar heaped in the center.  Add the
vinegar onto the sugar.  Add the Mustard, Laos, Ginger, Dragon, and the Garlic.  Mix well. 
Let stand for about at least 1 hour.  After one hour: peel the cucumber and slice 
it thinly, then add to the dressing. Mix well, let stand another 15 minutes or so and 
keep mixing a couple times.

My personal preference (and my Dad's) is the 'Made-in-France' semi-coarse mustard but you 
can subsitute whatever you like.  The closest I found was "French's Mustard".  You can 
also add a bit of tomato ketchup to suit your personal taste but don't let it dominate 
the mustard or the dressing as a whole!  About a tablespoon per cucumber is good.
