Keep the straws from unwanted drink bottles

If you have a drink bottle with an internal straw, when the bottle cracks, leaks or dies, don't throw the straw out! Remove it from the bottle and keep it in your cutlery drawer for whenever you need a straw, or keep a couple in your bag for use when you're out. I keep three in a little cotton bag in my handbag for when we order a drink that would normally come with a disposable straw (milkshakes, iced coffees, spiders, soft drinks). After use, I just give the straw a quick rinse in the restroom sink, or wrap in a serviette, and give a good wash when I get home. A simple way to reduce waste and help the planet!

Many meals from one rolled roast

I have found a way to get maximum meals and value from one single rolled roast. I bought a rolled pork roast which was way too big for just the two of us. Not wanting to be living on leftovers all week, I decided to cut it in half before cooking it. As I was about to place the uncooked half in the freezer, I decided to cut it into thinner slices and use the meat as pork chops instead. This has worked well! I also plan to cut the rolled roast into chunks in future, to use for stir fry, sweet and sour pork and so on. Normally you could never get pork chops or stir fry for $7.99 a kilo! There's no reason why you couldn't use this method with other rolled roasts too.

Sometimes we all have to just make do!

At 12 years old, my daughter is already helping our family save money on snacks using her Simple Savings skills! With five children in the house, we do a big shop just once a month and are careful to make our food and treats last until the next shop. Recently we were nearing the end of the month and getting low on food. I arrived home one day to find my daughter baking biscuits. 'They're Doos!' she told me. 'You always said if there was nothing in the cupboard, we had to make do, so I made Doos!'

The name has stuck in our house and now whenever we have 'nothing' in the house for lunch boxes, snacks or afternoon tea, she just makes a batch of 'Doos' using whatever she can find in the pantry to 'make do' with. She is proving to be very inventive with her recipes and is turning out to be a real baker. She'll turn out simple but delicious treats such as honey joys, choc chip biscuits, Anzac biscuits, pikelets and pancakes in no time at all! She really has shown that you can make something from almost anything in the pantry and would be wonderful at the $21 Challenge! Here is the recipe for her latest creation, called 'Sort of Scones!'

1 cup oats
1 cup self raising flour
1/2 cup sugar
125g butter
1 egg
1/4 cup milk

Mix all ingredients together, then roll into balls and place on a greased baking tray. Bake in a moderate oven (around 180C) for 10 minutes.

I couldn't be prouder of my daughter's efforts to help us save money and keep everyone well fed. Whenever we think our parenting has a lot to be desired, it's moments like this which prove we have to be doing something right - good things do rub off too!

One tablespoon only per wash

Slash your washing powder costs by using a tablespoon of washing powder in your machine instead of a scoop. It works just as well! My sister was learning about budgeting and the speaker mentioned that you could get the same wash results by using one flat tablespoon of washing powder as you could if you used a whole scoop. I decided to test this theory and found that even with a full load of washing this proved to be true. I buy a top brand washing powder that costs around $10 per two kilo box and it contains around 148 tablespoons. I used to go through a two kilo box of powder every four to six weeks when I was using a scoop. Generally I do a load of washing every second day, so using one tablespoon per wash, my box of washing powder should now last me nearly 10 months! Just changing this small habit will save me $90 every 10 months on washing powder!
