Preheat your oven to 175 degrees Celcius or 347 Fahrenheit. Once your pomtayer has thawed out place it in a bowl and add all the chopped celery leaves, sugar, lemon + orange juice, 5 spice and piccalilli and salt to taste. Give everything a big stir and make sure everything is mixed together. If you cant get pomtayer you can use 1 kilo of grated taro root.
In a greased oven dish add half of the pom mixture, top this with the tofu, but safe the sauce.
Top the tofu with the remaining pom. Top it all of with the sauce and a few bits of vegan butter or margarine (maybe you could use coconut oil)
Place them pom in the preheated oven and cook for 90/100 minutes, you can rotate the pom halfway through so front and back get equal heat.
When u poke it with a fork or skewer and its a little bit firm you are done! sever this with some rice and vegetables or put it on a bread roll with sambal and pickled cucumber.
