(Castrezana, DIS, 1998) for Drosophila nigrospiracula and Drosophila mettleri

(Makes approximately 24 glass bottles)

Cooking instructions for a stove top:

  1. Put the finely ground potato buds in a large Ziploc bag.
  2. Add autoclaved Saguaro and de-ionized water to a blender. Blend at high speed, approximately 60 seconds. Make sure texture of blended solution is smooth and creamy. Make sure there are no chunks of Saguaro.
  3. Pour blended mixture into a medium sized pot. Bring mixture to approximately 90°C (small bubbles, no boil).
  4. Allow mixture to cool on a cold stove top burner to 60°C. (Watch closely -- this will happen quickly). Stir continuously.
  5. Add propionic acid to mixture.
  6. At 60°C, pour hot cactus suspension into large Ziploc bag containing the potato buds.
  7. Knead/mix thoroughly to uniform consistency.
  8. Cut a corner of the Ziploc bag and dispense by squeezing into glass bottles. Squeeze approximately 79 mL or 1/3 cup of mixture into each bottle.
