sorry, it's called repashy superfly. there is also this home grown ff culture that a friend sent me. he has been using it for about 5 years now and never had a problem (or so he claims)
1 cup banana (about 2 bananas)
1 cup apple sauce
1/8 cup vinegar (or 2 tablespoons or 15 ml)
2 cups oatmeal
Put the banana and apple sauce in blender or bowl and mix until the banana
is liquefied. Heat in the microwave for approximately 2 min. or until hot
enough to kill off any wild fruit fly eggs that were in the bananas, and to
reduce mold. Add the vinegar and mix in oatmeal until it becomes firm, but
still moist. I then put the mixture into a large freezer bag and keep it in
the fridge.

When it's time to make a culture, I scoop what I need and put it in the
culture container (usually microwaving it a bit to warm it up). I then sprinkle
a few pinches of bakers yeast on top.
