Tech Specs: Canon 70D (F11, 1/60, ISO 200) + a Canon EF-S 60mm macro lens with 37mm of extension + a diffused MT-24EX (-1 FEC). This is a single, uncropped, frame taken hand held.
Technique: I used a syringe with a .8mm diameter needle to inject 2:1 sugar syrup into a Basil flower. You can get bigger needles, but .8mm is a good compromise between being small enough to get into most flowers and yet big enough for thick liquids. Ignore the shutter -the flash is the only significant light source on the subject. I dragged the shutter to get more detail in the background.
