Heat the oil in a heavy-based pan, add the panir and
fry until golden, turning gently and taking care not
to burn it. Remove from the pan and set aside.
Add the onions to the pan and fry until
colored,
then remove and set aside. Add the measured water,
and salt to taste, to the pan and bring to the boil.
Add the peas and sugar, cover and simmer until the
peas are almost tender. If necessary, uncover and
cook for 1 minute to evaporate any liquid.
Return
the onions to the pan, add the ginger and chilies,
and stir well. Cook for 2 minutes, then very gently
stir in the panir.
Heat through for 2 minutes, then
stir in the garam masala and coriander. Serve
immediately.
