Full strength DIY 'Dettol' spray for just 2c a bottle!

A little supermarket research led me to making a huge saving on keeping germs at bay! When my two young children had a gastro bug, I needed anti-bacterial spray to clean up and stop the spread of germs, which vinegar didn't touch. The cheapest anti-bacterial spray I could find was Dettol anti-bacterial spray which cost $4.20 for 500ml. On reading the active ingredients it said it contained Benzalkonium Chloride 0.095%. Then, I saw that a bottle of Coles brand disinfectant was $1.40 for two litres. I read the ingredients and saw Benzalkonium Chloride 1%. The instructions said to dilute it in a ratio of 1:20, or 30ml to 600ml water. So I bought that one, made up the solution and put it in an old spray bottle I already had. It worked just as well and cost just over 2c per spray bottle of prepared solution, compared to $4.20 for the Dettol spray! While Coles brand disinfectant says it can only be used on “floors, walls, bathroom and toilet areas”, not in kitchen areas like the Dettol spray, for me these were the only areas that I needed to disinfect and worked a treat!

Berry nice savings to be had on blueberries!

I have found the answer to enjoying the health benefits of blueberries is in the freezer aisle! Blueberries are so good for you, but very expensive if you buy the punnets of fresh fruit. The regular price of fresh ones works out at well over $30 per kilo and while they look nice on a fruit platter, they don't have a lot of flavour. Instead, I now buy frozen blueberries at around $4 or $5 per 500g pack - less than a third the price! Simply throw a cupful in the microwave with a teaspoon of sugar and zap for a minute or two. Much tastier and are delicious with ice cream, natural yoghurt or just on their own!

Handy pillowcases make for a tidy linen cupboard!

I have saved myself the frustration of constantly losing items from my sheet sets (and the expense of having to buy replacements) by keeping them all together in a simple but ingenious way! I used to be constantly searching for a full set of sheets and pillowcases in my linen cupboard no matter how many times I tidied it up. It's crazy but, in my frustration, I actually found myself buying new sets! Knowing this wasn't a real solution I finally pulled everything out, put all the sets together and placed all the sheets and extra pillowcases inside one matching pillowcase. Since then I haven't lost a single item! I can easily see my sheets and duvet sets and the kids can now find their sets and make their beds on their own.

Student secrets to eating for $15 a week

During my uni student years I developed a menu-planning and grocery shopping system that allowed me the freedom to eat well, generously fuel my bicycle-based lifestyle, entertain guests regularly and experiment with new recipes, all within my strict food budget of just $15 a week!

It works like this.

1. Decide how much you will spend on your weekly groceries. In recent years I have had to increase my spending to about $21 a week due to rising food costs and CPI, but the system still works really well when I use it and is a great way to separate needs from wants.

2. Choose the staples and basics that are to be made every week as needed. These could include soy milk, tofu, sourdough bread, yoghurt, sprouts, hummus, fresh lemon cordial, Anzac bickies, gomasio or whatever else you require.

3. Give the ingredients needed to make these staples first priority when making the weekly shopping list. If you have a local food co-op you can buy mostly organic ingredients with minimal packaging in exactly the amounts you need.

4. Check what else is in the fridge, cupboard, garden or neighbours' garden and pore over your large collection of second-hand recipe books to see what can be created with these other ingredients. Recipes which require two or less extra (and inexpensive) ingredients are preferred and a list of these and their corresponding cookbooks/page numbers is made and stuck on the fridge. There will usually be a selection of mains, side dishes, desserts, treats and beverages on the list.

5. Give the extra ingredients needed for the chosen recipes next priority on the shopping list. Over time you will intuitively know when your shopping list is 'full'.

6. Once out shopping, specials of the day such as a big bag of discounted apples or cheap cooking tomatoes take third priority. If not consumed within the week, these can form the basis of recipes chosen for the following week.

7. Last priority (and usually only considered after the register shows you are still under budget) are those inevitable temptations that one wants rather than needs. It often helps me to take my recipe list with me and remind myself that I can make a delicious self-saucing carob pudding at home for a fraction of the cost of the tiny chocolate bar I am now contemplating. All of a sudden the money seems much better spent on a kilo of brown rice!

8. Back at home, simply cross the recipes off the list as they are made. There will always be plenty of food for dinner parties or last-minute guests, and the sometimes tiresome decision of 'what to cook?' becomes easy.

Using this system I have never run out of food or felt like there was 'nothing to eat'. In contrast, I have stayed at many houses where, despite having pantries and fridges which are bursting with food, the occupants have driven to the supermarket and easily spent $30 or $40 just to cook up dinner for the night.

Seems unbelievable? Try scratching every processed food item off your own shopping list and see how many more kilos of real food you can come home with for the same amount of money. Don't forget too, to keep an eye out for trees in public areas which are loaded with fruit or nuts. I have used the $15 a week food budget for stretches of up to a year at a time, which means I certainly wasn't relying on stockpiles of food from more extravagant days tiding me over. Necessity breeds creativity, and I am so happy to have been forced early on to examine and separate my wants from my needs in this regard. Even when times are tough, I know I can eat well!
