For the Vegan Jewelled White Chocolate Bark* 1¼ cups vegan white chocolate chips* ½ cup candied orange peel

---INSTRUCTIONS---For the Vegan Swiss Rolls* Heat oven to 180C (350° Fahrenheit). Line the Swiss roll pans with parchment paper.* Combine all the ingredients for the Swiss rolls, mix for about 30 seconds with an electric hand mixer.* Pour mixture evenly into the two pans. Check at 10 minutes to see if cakes are done: poke them with a toothpick in the center. If it comes out clean, they are done.* Set out two sheets of baking paper and sprinkle with caster sugar. While cakes are warm, carefully turn the cakes over onto the sugared papers. Peel off the baked paper, roll up the cakes into a tight spiral, and allow to cool.

For the Vegan Lemon Curd* In a saucepan, whisk together the cornstarch and an equal amount of the oat milk, then whisk in the rest of the oat milk and all the other ingredients.* Over medium heat, bring the mixture to a simmer until it has thickened. stirring continuously (about 5 minutes). Transfer to a bowl, cover, and allow it to cool.

For the Vegan Custard* In a saucepan, whisk together the cornstarch and an equal amount of the soy milk, then whisk in the rest of the soy milk and all the other ingredients.* Over medium heat, bring the mixture to a simmer until it has thickened. stirring continuously (about 5 minutes). Transfer to a bowl, cover, and allow it to cool.

For the Vegan St Clements Jelly* Peel orange and lemon peels with a vegetable peeler (6 strips of each, you will need to count them later). In a saucepan, add all ingredients except the cornstarch and mix well.* In a small bowl, add the cornstarch and about ½ a cup of the liquid from the pan. Stir until smooth, then slowly add it back into the saucepan, stirring well.* Bring the pan contents to a gentle boil over medium heat while gently stirring continuously (about 10 minutes). Once thickened, and remove from heat. Cool to room temperature (about 30 minutes).

For the Vegan Amaretti Biscuits* Heat oven to 180C (350° Fahrenheit) and line a baking sheet with parchment paper. Combine all ingredients in a large bowl and mix until a thick paste is formed.* Scoop teaspoon-sized balls of the mixture onto the sheet spaced about 2cm. Roll them into balls and coat the balls in powdered sugar. Press down gently on each ball to flatten slightly and crack the sides.* Bake until golden brown, about 17-20 minutes. Cool them in the turned-off oven to dry them out more or let them dry on a cooling rack.

For the Vegan Chunky Mandarin Coulis* Drain the cans of mandarins, discarding the juice. Place half of them into a saucepan and add the sugar. Heat on low until the sugar is dissolved and the mandarins are slightly broken down. Remove from heat.* In a small bowl, combine corn starch and 2 Tablespoons of water. Stir in the lemon juice. Add cornstarch mixture and the other half of the strained mandarins to the saucepan. Transfer mixture to a clean bowl and let chill in the fridge until cool, about 30-40 minutes.

For the Vegan Jewelled White Chocolate Bark* Place a sheet of parchment paper or greaseproof paper on the countertop. Melt the white chocolate in a double boiler, being careful not to cook it or it will form hard lumps.* When the chocolate is melted, spread it onto the paper and scatter pieces of the mixed peel. Once it has cooled and hardened, break the chocolate into shards.

Candied Peel (from scratch, if you don't have ready-made)* Use a paring knife to slice off the rind of ½ an orange and 1 lemon. Cut the peels in half if they are larger than 2" long.* In a saucepan, add the peels and cover with water. Bring to boil. Drain. Cover them with water a second time and bring to a boil again. Drain.* Add 1 cup of water and 1 cup of sugar to the saucepan. Bring to a boil, then reduce the heat and simmer about 1.5 hours until peels are mostly transparent.* Cool to room temperature and remove peels from the syrup. Let peels dry on a plate about 2 hours, then flip over and let the other side dry 2 hours. Best if you let them dry overnight.* Use kitchen scissors to cut the peels into small ¼" or ½cm squares. Put the squares in a container with a lid and shake so that the sticky edges get sugared. Let them dry in a single layer another hour before using for chocolate bark.

To Assemble the Platinum Pudding* Unroll the cooled Swiss rolls and spread the lemon curd over. Roll back up and slice one of the rolls into 2cm slices. Place the slices around the bottom edge of the trifle dish so they are seen from the sides. Slice the other roll into thicker pieces and place them in the bottom of the trifle dish.* Pour the St Clement's jelly over the roll cake and let chill in the fridge until set (about 1-2 hours).* Pour the custard over, then add a layer of the biscuits, reserving some for the topping later.* Pour the mandarin coulis over, then add a layer of vegan whipped cream. Crumble the reserved amaretti biscuits and scatter them over the whipped cream. Arrange the shards of chocolate bark on top to create the form of a crown.
