For 6 hefty hamburgers:
500gr/ 1,1 pound ground beef
1,5 red onion, finely chopped
4 garlic cloves, finely chopped
3cm ginger, grated
1 big egg
4 tablespoons sweet soy sauce (kecap manis)
1 tablespoon sambal chilli paste (kecap)
1,5 teaspoon shrimp paste (trassi)
1,5 teaspoon ground coriander (ketumbar)
1,5 teaspoon ground galangal (laos)
1 teaspoon ground cumin (djintan)
0,5 teaspoon ground nutmeg
6 tablespoons breadcrumbs
For the buns:
4 large soft wholegrain hamburger buns
Acar Ketimun (pickled cucumber, see recipe)
Couple of radishes, thinly sliced
Spanish (or other) chilli, deseeded
Spring onion, only the (light)green part, finely sliced
For the sauce:
5 tablespoons mayonnaise
2 tablespoons sambal kecap (or another chilli sauce)
Juice of half a lime
Pepper and salt to taste
Grill or grill pan
Finely chop the onion and garlic. Peel ginger with a teaspoon and grate. Heat oil in a frying pan and fry onion until translucent. Add garlic and ginger, sambal chilli paste and trassi shrimp paste and fry for another 2 minutes.
Add ground beef to a mixing bowl and add the onion mixture. Wait until the mixture cools down and add ground coriander, galangal, cumin, nutmeg and kecap. Mix well.
Break the egg over the ground beef mixture and add breadcrumbs. Mix well and look if the mixture isn’t too wet. If it’s too wet add some more breadcrumbs and mix well until it forms a dryer ground beef mixture.
Knead 6 meatballs with your hands, place on a board and apply some pressure in order to create the desired hamburgers.
Heat a grill (level 2) or heat a grill pan over medium heat. Add the hamburgers, turn the heat a bit lower (medium-low) and fry the hamburgers for 10 minutes and turn them a couple of times.
Meanwhile, mix mayonnaise with sambal chilli paste (or another chilli paste) and lime juice and mix well. Add salt and pepper to taste.
Cut the hamburger buns in half and heat for 2 minutes on the grill or in the grill pan until the buns are a little browned.
Spread both sides of the hamburger buns with the sambal-lime-mayonnaise. Place a few leaves of lettuce on the hamburger bun, then add the hamburger, pickled cucumber slices, radish slices, spring onion and finely chopped chilli.
