If the pudding is too lumpy, sift in some cocoa powder or cornstarch for texture fix.
If the pudding is too thick, add some egg yolk for custard-like thickness.
Use a combination of high-quality dark chocolate and cocoa powder.
Cook the pudding on low heat slowly to avoid grainy and curdled texture.
For freezing, cover the pudding container with a plastic film to prevent rubbery texture.
If pudding is overly sweet, fix it with dark chocolate or if it's too bitter, add some honey.
To enhance the depth of flavor, add a pinch of sea salt.
