Just one

So you are confronted with a choice three tangy sourish cousins sit looking at  you from the door of the fridge.  Each calls to you numbering their assets and why you should chose them as a building block to your sandwich. You have already discarded Honey Mustard as far to sweet to compliment your Dagwood stack but now you have the unenviable task of weeding out 2 of the three.  Who ya gonna chose?  You can only take one mustard to the dance…pick wisely.
