I succeeded at YOGURT!!!!

My yogurt recipe finally succeeded after 3 tries!!!! Here's the final one:

1. Use PAUL's or Nestle plain yoghurt. (I used Nestle cuz it's much cheaper)
2. To begin your own batch, use 1 tablespoon for every 500ml of milk.
3. Scald milk to just bubbling and steam appearing.
4. Let cool to lukewarm - when you can stick your finger in and leave it there without feeling painful for 10 seconds, it's the right temperature. Alternatively, if you have a thermometer - when it reads 40-44 deg C.
5. Stir a bit of warm milk into the yogurt in a separate container and ensure the yogurt 'dissolves'.
6. Gently mix this into the main bulk of the yogurt-to-be.
7. Put into conventional oven, and set the temperature at 40 deg C and allow to set for 8-12 hours. Leave uncovered and door shut.
8. Yogurt is ready when it "feels" like yogurt (I could tip the container over and it was thick and creamy!! Yippeee!!!).
9. I monitored the temperature every hour or so (with my thermometer left inside the oven).
10. At 40 deg C, setting takes approximately 8 hrs.
11. Chill in fridge once done.
    

If you have no thermometer or oven - put the lukewarm yogurt-t0-be into a thermos or whatever container that will keep its temperature in the range 36-44 deg C for at least 5 hrs.
