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

What each ingredient does

Green beans
Provide the crisp, firm base that the brine flavours and holds its texture through pickling.
White wine vinegar
Adds sharp acidity that gives the pickle its tang and helps preserve the beans.
Mace
Adds a warm, aromatic spice flavour to the brine.
Ginger
Adds a warm, aromatic bite that gives the pickle depth.
Pepper
Adds a sharp, aromatic heat that seasons the brine.

The step that matters

Pouring the hot pickle over the beans. The brine must be boiled so the vinegar and spices are fully infused before it goes over the beans. Hot liquid carries flavour into the vegetables more readily than cool liquid, and the acid in the brine is what keeps the pickle stable.

Swap the mace
