Soto Ayam Lamongan with Koya
East Java's richer soto: a deep broth from charred aromatics fried in chicken fat, finished with koya, a savoury powder of fried garlic and prawn crackers.
Method
Put the peeled and halved shallots, garlic, candlenuts and sliced ginger in a dry pan and roast over medium heat for , turning them now and then, until charred in spots and softened.

Fry for , stirring, and lift out the moment it turns pale gold; brown garlic tastes bitter, and it keeps cooking after you remove it. Keep any water away from the oil. Grind the cooled garlic with the prawn crackers to a fine powder in a blender or mortar. Sambal: boil the chilies and the sambal garlic in water for 3 minutes, drain, pound with the salt and loosen with 1 tablespoon of broth.

high heatLift out the chicken, shred it roughly and discard the bones. Put noodles, cabbage, sprouts, chicken and a halved egg in each bowl and ladle over piping hot broth.

Cook's tip
Koya stays crisp for a week in an airtight jar and is great sprinkled on fried rice or salads too. If the broth reduces too fast, top it up with a little hot water. Shredding the chicken skin into the bowl is closer to the Lamongan style.
Cooking it at camp
Make the spice paste, koya and sambal at home. At the campsite, sear the chicken, fry the paste in the same pot, add water and simmer. If a long simmer is impractical, boneless thighs are done in 25 minutes.
