Using a primary shot of overproof white rum makes it a nuclear daiquiri, adding a Smith & Cross secondary makes it thermonuclear. No idea why this was originally made with Yellow Chartreuse; just because it 's yellow (Strega??) it doesn't necessarily belong in a banana daiquiri. As others have noted, Creme de Banane (I had Tempus Fugit) works much better. I also think splitting the citrus between lime & lemon works better, and I didn't miss the Xanthan gum. I did add a couple dashes of pimento dram, though. Finally, this clearly belongs in a tiki mug.
