Recipe for fruit flies
Ingredients: 400cc water, 1 banana (or 125g other one sweetens fruit), oat malt 200-250g, 3 coffee spoons leaven or 10g fresh baker leaven, 5 beer leaven tablets, nipagine(ethyl p oxybenzoaat, E 214) to obtain in pharmacy, gelatine sheet 3g, house keeping vinegar or apple vinegar, syrup (with apples, pears and dates).
Working method: Put the water in a pot with the gelatine sheets, put the pot on a small fire and rudder the banana in to it. When it boils put the oat malt in it. Let it boil for a few seconds and take the pot of the fire. Leave it to cool down. (best way to do it is in a tube of cold water) Flatten the beer leaven tablets. If the temperature for the mixture is about 40°c you can put in the syrup. Rudder and put in the fresh baker leaven, beer leaven and a little bit of nipagine. Rudder very good now and leave the mixture leavens for about 10-12 hours in a hot place. After that mix the mixture fine, you can add a little water if necessary. Don't make it to fine so the flies don't drown in it.
That should do the trick.
