Why it works: Pepper and ginger match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 6,800 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
To Pickle French Beans
Ingredients
Directions
Gather French beans before they become stringy, without taking off the ends.
Soak them in a very strong brine until they turn yellow.
Drain the brine and wipe the beans dry with a cloth.
Place the beans in a stone jar by the fire, add a little alum, and pour boiling vinegar over them every 24 hours, sealing to prevent steam escape.
In 4 to 5 days, the beans will turn green.
Boil a little mace, whole pepper, and ginger in the vinegar.
