Preheat the oven to 180 °C (356 °F). Lightly dust a baking tray (or the back of a baking tray) with flour and set aside.
Make the tomato-based dough: in a large bowl combine 12 tbsp oil, 12 tbsp tomato juice, 1 tsp ammonium (dissolved in a tablespoon of the tomato juice if it is powdered), and a pinch of salt. Gradually add 450 g flour and mix until you obtain an elastic dough. Do not add extra ingredients.
Divide the dough into four equal pieces. Roll each piece thinly to the size of your baking tray. Place each rolled sheet onto the prepared floured tray (one at a time) and bake for about 7 minutes at 180 °C, until the sheet is set and just lightly colored. Cool the baked sheets on a rack.
Zest and juice the 2 lemons. Reserve the lemon peel (zest) to add to the milk in step 6. Split the lemon juice roughly in half: one half for the Turkish Delight butter mixture (step 5) and the other half for the semolina cream (step 6).
Prepare the Turkish Delight butter mixture (for the top): beat 1 pack butter (82% fat) with 6 tbsp powdered sugar until light and foamy. Finely mash or chop 700 g Turkish Delight and mix it into the foamed butter along with half of the lemon juice reserved in step 4. Stir until homogenous and set aside at room temperature.
Make the semolina-coconut cream: in a saucepan combine 1 L milk, 5 tbsp sugar, and the lemon peel (zest) reserved in step 4. Bring to a boil over medium heat. When the milk is boiling, gradually add 200 g semolina while stirring constantly to avoid lumps. Continue to stir and cook until the mixture thickens and comes back to a boil.
After removing the pan from the heat, while the semolina cream is still warm stir in 250 g butter (82% fat) and the remaining half of the lemon juice reserved in step 4. Mix until the butter is fully incorporated. Let the semolina cream cool completely, then stir in 100 g coconut.
Assembly: place the first baked sheet on a serving tray. Spread half of the cooled semolina-coconut cream evenly over it. Place the second sheet on top and spread 400 g apricot jam evenly over that layer. Place the third sheet on top and spread the remaining half of the semolina-coconut cream evenly. Finish with the fourth baked sheet.
Spread the Turkish Delight butter mixture (from step 5) evenly over the top sheet. If you wish, dust lightly with any remaining powdered sugar you have available (note: powdered sugar has already been used in step 5).
Cover the assembled cake, refrigerate, and leave overnight to set. Slice and serve the next day.
