Mike from Auckland has a power-saving tip for those who are technically inclined. "If you have a mains cylinder fit a 350kpa limiting valve instead of the normal 500kpa. You will barely notice the difference but will save lots of water in the shower. A high-flow shower head will more than offset the felt loss of pressure and all valves will operate as normal."
Laura from Otago likes ricotta but does not want to pay the super expensive price. She says it's cheap and easy to make. "Heat two litres or even one litre of blue top milk (don't use trim as you get less yield) to 90 degrees, take off the heat and pour in one to two tablespoons of white vinegar or lemon juice. You will see the milk separate into curds and whey. Strain off the curds (ricotta), refrigerate, or eat straight away. The whey is great for the garden."
Linda from Paraparaumu suggests milk powder. "It tastes great and (trim milk) only costs $1 a litre.
"You can buy a Homebrand pack at Countdown for $10 that makes 10 litres. The advantage is that you only make up what you need. Good for the environment as you are not using milk containers. We don't notice any difference in the flavour."
Cole from Auckland has a tip about broccoli. "Once you have cut the head off your broccoli plant, instead of pulling it out and starting again, leave it in. Smaller heads grow out just above where the leaves join the stem. You can keep eating broccoli for months. I did this a few years ago and we ate broccoli at least two or three times a week for about four months off eight broccoli plants."
