To create mixed fruit jelly from pineapple, orange, lemon, gelatin, and sugar, the following materials and methods may be used:

Materials:
1. Pineapple
2. Orange

Methods:

1. Prepare the fruits: Start by peeling and cutting the pineapple, orange, and lemon into small, uniform pieces. Remove any seeds or pits from the fruits.

2. Boil the fruits: Place the chopped fruits in a saucepan with water and bring it to a boil. Allow the fruits to cook until they are soft and the juices have been released. This should take about 10-15 minutes.

3. Blend the fruits: Once the fruits are cooked, remove them from the heat and let them cool slightly. Transfer the fruits to a blender or food processor and puree them until smooth. Strain the puree through a fine sieve to remove any pulp or solids.

4. Make the gelatin mixture: In a separate saucepan, combine gelatin and water according to the instructions on the gelatin package. Heat the mixture over low heat, stirring constantly until the gelatin has completely dissolved.

5. Mix the fruit puree and gelatin: Pour the fruit puree into the gelatin mixture and stir well to combine. Add sugar to taste and continue to stir until the sugar has dissolved completely.

6. Pour into molds: Lightly grease molds or containers with cooking spray and pour the fruit jelly mixture into them. Place the molds in the refrigerator and let the jelly set for at least 4-6 hours, or overnight.

7. Serve: Once the jelly has set, carefully remove it from the molds and serve chilled. You can enjoy the mixed fruit jelly on its own or use it as a topping for desserts like ice cream or yogurt.

By following these steps, you can create a delicious and refreshing mixed fruit jelly using pineapple, orange, lemon, gelatin, and sugar.
