Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated chocolate
- Melts into the base, giving the icing its flavour, body and glossy set.
- Powdered sugar
- Dissolves into the melted chocolate, sweetening it and thickening the icing to a smooth texture.
The step that matters
Melt the chocolate over boiling water. Chocolate scorches or seizes into a grainy lump if it gets too hot. Gentle indirect heat from simmering water melts it evenly so the icing stays smooth.
