Pig's Trotters and Ginger Vinegar Stew

Timeabout 20 minutes simmering

Ingredients

4 pigs trotters
12 large eggs
500 g ginger root
Enough sweet black vinegar to cover your other ingredients

Directions

Prepare the eggs and ginger

Hard boil the eggs, refresh and set aside to cool.
Wash, peel and thickly slice the ginger, bruise with the flat of a knife.
Fry the ginger at high heat with oil and salt for about 5 minutes. Set the fried ginger aside.

Prepare the trotters

Remove hair from trotters by singeing with an open flame and scraping away.
Remove trotters from water when skin has tightened and exterior changed colour. Refresh trotters with cold water until cooled.
Put trotters aside to drain. Dry trotters with a clean cloth.
Section trotters first across joints and then lengthwise.
Rub trotters with salt.

Cook the stew

Heat a frying pan or wok. Brown trotters in their own fat.
Place ginger and trotters into the pot. Add sweet vinegar.
Bring the mixture to a boil. Lower the heat and simmer for about 20 minutes.
Peel eggs. Add eggs to pot. Continue simmering for 10 minutes.

Set the jelly

Remove stew from heat and set aside for a day. Occasionally warm gently over low heat.
Bring to a simmer and allow to cool again. Repeat heating and cooling three times over the course of a day.
The stew will set into a jelly.

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

What each ingredient does

Pig's trotters: Collagen-rich skin and connective tissue melt into gelatin, giving the stew its body and jelly set.
Eggs: Hard-boiled eggs add richness and a firm, mild texture to the finished stew.
Ginger root: Its sharp aromatic compounds cut through the richness of the fat and skin.
Sweet black vinegar: Acidity balances the rich pork fat and adds a deep, mellow flavour.

The step that matters

Repeated heating and cooling to set the jelly. Gelatin from the trotters' skin and connective tissue only sets into a firm jelly once it is cooled after gentle heating. Repeating the cycle helps it fully set, so the stew should be cooled completely between warmings.
