Ingredients: whole milk lemon or fresh chilli Method: boil the milk and cool it down pour in a small bowl, add chilli with stem or cut one side of lemon and dip in the milk do not squeeze the lemon juice out half cover the bowl leave it in a warm place until thickens (15-20 hours) this is the primary culture. you can use 1tsp culture per 1/2cup of milk to make secondary culture. the secondery culture you can use to make actual yogurt. Notes: * Don't cover the bowl completely, keep a little opening so that the bacteria in the air can go in. *although mine took three days to achieve the perfect yogurt, yours could take more because this is natural bacteria from the air causing the progress, It depends on how much bacteria present in the environment and the supportive weather, so the time limit may vary. *use a small amount of milk until you get the right taste so that you don't waste a lot of milk. -
