Directions

  1. Before you begin, it’s important to note that the container you choose must be suitable for all of your ingredients. ≈ 3 min
  2. It shouldn’t be changed during the preparation process. ≈ 3 min
  3. I use a measuring cup for all of my ingredients. ≈ 3 min
  4. For example, if you are using a measuring cup, you need to measure all the ingredients using the same cup. ≈ 3 min
  5. This amount of ingredients is sufficient for 4 to 6 people. ≈ 3 min
  6. Mix the starch with water until it dissolves. ≈ 3 min
  7. Next, mix the rice flour with milk, then pour both mixtures together and pass them through a sieve. ≈ 3 min
  8. It is best to prepare this corn cream in a cast iron or steel pot, so that it doesn’t stick to the sides and bottom. ≈ 3 min
  9. The ideal temperature for preparing this dough is low, as it is necessary to completely remove moisture from the rice flour. ≈ 3 min
  10. Do not increase the temperature, even if you think it will speed up the cooking process, as this will not result in the desired flavor. ≈ 3 min
  11. If the dough needed to cook faster, we wouldn’t add as much milk and water.
  12. Pour the rice flour, cornstarch, and water into a pot, then place the pot on a low heat. ≈ 3 min
  13. It is important to constantly stir the mixture, as otherwise, the rice flour and starch will quickly settle at the bottom of the pot and form a paste. ≈ 4 min
  14. Therefore, it is important to exercise regularly. ≈ 4 min
  15. Once the mixture has reached a certain consistency, we add the sugar and rose water, and continue to mix until it is completely thick. ≈ 4 min
  16. Its consistency is ideal: not too liquid, not too thick, just the right consistency. ≈ 3 min
  17. You know, like the egg whites you whisk to make a cake, they need to remain slightly moist. ≈ 4 min
  18. In this case, once the stirring spoon has almost reached the bottom of the bowl, it’s ready. ≈ 4 min
  19. I hope you can clearly see in the photo that some of the ingredients I added remain separate and haven’t mixed with the rest. ≈ 3 min
  20. Remove the jam from the fire. ≈ 3 min
  21. We divide the ingredients in half: one half is white, and the other half is filled with a very concentrated saffron, which will not affect the color of the water. ≈ 3 min
  22. The container used to prepare “tarhulwa” must have edges. ≈ 3 min
  23. First, immerse the container in cold water, then add the white ingredients.
  24. We can pour the yellow ingredients over the white ingredients, or divide them into two separate containers. ≈ 3 min
  25. We can also decorate the top with pistachio powder or chopped pistachios. ≈ 2 min
  26. Let it rest in the refrigerator for a few hours before serving.
  27. First, we remove the tørhalwa from the container using a knife and cut it into pieces. ≈ 3 min
  28. The cutting is easy, and then it can be removed from the container. ≈ 3 min
  29. The traditional method involved preparing two types of plates: one white and one yellow. ≈ 3 min
  30. Furthermore, during the sale, the two items were sold together at a fixed price. ≈ 3 min
  31. If you missed noticing the formation of lumps during cooking, and some ingredients have settled at the bottom of the pot, empty everything into another container. ≈ 8 min
  32. This will help to prevent scratching the cast iron or stainless steel container. ≈ 3 min
  33. Next, use a stainless steel whisk to stir and break up any remaining clumps, then return the ingredients to the original pot. ≈ 4 min
  34. Do not add milk or water to these ingredients, as it is no longer possible to guarantee that the result will be correct. ≈ 3 min
