Water normally takes about 10 minutes to boil.

Avoid grating the vegetables, as this causes them to cook too quickly and makes it hard to parboil them.

If you are parboiling an entire cauliflower, leave it in the boiling water for 8 minutes.

If you are parboiling larger pieces of potato, simply increase the cooking time a little. For example, if your potatoes are in 3 centimetres (1. 2 in) cubes, boil them for 15 minutes. Parboiled potatoes are great for roasting and making hashbrowns with.

This technique can be used on all types of edible mushrooms.

If you like, add a pinch of salt to accentuate the flavours in the meat.

Parboil a whole chicken for 30-40 minutes. Parboil a chicken breast for 10 minutes and parboil legs, thighs, and quarters for 5 minutes.

Avoid parboiling other cuts of pork and beef, as it can make the meat too chewy.

Put a lid on the saucepan to help it boil faster.

Only cook 1 type at a time, as different types of rice have different cooking times.

Parboiled brown rice is great for making brown rice risotto and rice salad.
