Wash the rice in a sieve under cold water, then
leave to drain for about 15 minutes.
Heat the oil in a large saucepan and fry the onion
for a few minutes over a moderate heat until just
soft.
Add the rice and stir-fry for about 10 minutes,
taking care to keep stirring all the time so that
the rice doesn't stick to the base of the pan.
Add the stock or water and garlic and stir well.
Bring to the boil and cook over a high heat for 5
minutes, then reduce the heat, cover with a
tight-fitting lid and cook the rice for 20 minutes.
Scatter the corn over the rice, then spread the
paper on top and lastly sprinkle over the grated
carrot.
Cover tightly and steam over a low heat until the
rice is cooked, then mix together with a fork and
serve immediately.
