If you prefer, you can make up your own Madras curry powder using 1 tsp each ground coriander, cumin and garam masala and ½ tsp chilli powder.
In a large bowl, mix together the turkey
mince, onion, garlic, curry powder, coriander
and egg yolk with a little salt and pepper.
Combine well with your hands, then shape
into 4 flat burger patties.
Heat the oil in a frying pan over a high heat,
then cook the burgers for 5 mins each side
or until cooked through. Toast the cut sides
of the burger buns. Place the salad on the
bottom halves of the warm buns, then top
with the burgers and chutney or lime pickle.
