Let's start preparing vegan custard. Put starch in a small saucepan. Heat milk and melt the rice malt into it. Pour in the milk over the starch stirring constantly, until it forms a smooth cream, without any lump.
Put the saucepan on the stove and bring to a boil, stirring quite often. While the custard reaches a boil, add turmeric, lemon zest and vanilla extract. Let the custard cook over low heat for a couple of minutes from the boil, stirring constantly. Turn off the heat and let the custard cool down.
When the custard has cooled down we are ready to assemble the tiramisu. Start filling a pan with a layer of rice cakes, soaked into red berries infusion. Put a layer of custard on them and distribute over some strawberry compote.
Repeat the layers again until you finish all the ingredients. I made 3 layers, and I ended up with the custard. Sprinkle with cocoa or carob powder.
Store the tiramisu into the fridge for at least a couple of hours before serving.
