Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the gluten network that gives the cracknels their structure.
Egg yolks
Add richness and help bind the stiff paste together.
Butter
Adds fat that tenderises the dough and enriches its flavour.
Rose water
Adds a floral aroma to the dough.
Nutmeg
Adds a warm, spiced aroma to the dough.

The step that matters

Boil until they float, then cool in cold water. Floating shows the pieces have set enough to hold their shape. The cold water bath stops the cooking so the outside firms up and the cracknels harden rather than stay soft.
