Mari has emailed asking about leftover chips – as in English chips eaten hot, thick fries not potato chips/crisps – saying her family nearly always have “eyes bigger than their bellies” when they order fish’n’chips and end up with some leftovers:

Good thick chips not just tiny hard scraps. It’s such a waste. Can anything be done with them?

Obviously the first thing here is to reduce the amount she & her family buy in the first place – but I realise chip portions are a variable thing. I read about a study recently that found that portion sizes could vary from between 250g (half a pound) to 1kg (2.2lbs!) depending on the shop and server. I think most families would have leftovers even if they bought just one bag of the latter!

Whenever my father (not) in law has leftover chips, he wraps them back up in their paper again and freezes them for a snack at a later time. I’m not sure how he defrosts/reheats them (and admittedly, he’s not got particularly high standards when it comes to cooking) but it might be worth experimenting with if you have them leftover regularly.

At the end of the day though, they’re just leftover fried potato – and can be reused like any other leftover potato. Mash up the softer ones – they could be used in fish cakes or a hash/bubble & squeak. The little hard ones could be chopped up and used as a crispy coating/topping.

Here, they’d go in our “misc stuff for the chickens” pile.

What would you do with leftover chips?

Joel has an old toaster oven and would like ideas on how he can reuse or recycle it:

My wife just bought a new toaster oven. The previous one had problems in her eyes, because the spring-loaded door didn’t work as smoothly as when new, and the unit, after three years, had a couple unsightliness issues.

The door is not much of a problem, as far as I’m concerned. It does stay shut reliably when you shut it. So, okay, now I’ve got this little heating unit that I can take to my shop. It seems the controls function as-new. Thermostat system works. Heats up to 450* F.

People are using old toaster ovens for flow soldering, for un-soldering components on circuit boards, and for powder-coating of small objects. Right now, I don’t do any of those things… but you never know

Got any other ideas as to how it can come in handy?

Toaster ovens aren’t very common in the UK but they seem to be mini table-top electric ovens – the bread is put on a horizontal tray for toasting but they can be used for other things too (much like any electric oven).

First things first, since it works well, do consider passing it on to someone is less concerned about the door/aesthetic issues — if your local thrift/op/charity shop doesn’t accept electronics, you could pass it onto someone else directly through your local Freecycle/Freegle group.

If that ship has sailed though and it’s needed to be removed from culinary service, it may still be ripe for random crafting reuse. It doesn’t go hot enough for things like clay pottering firing or enamelling (the latter of which is a shame because perhaps he could have fixed Su’s casserole pan… ;) ) but would be fine for the things Joel suggests or other low temperature crafts such as Fimo or the recycled equivalent of Shrinky Dinks (there seems to be a new trend for making pedants from plastic number 6 – (not expanded) polystyrene – cups).

Some gardeners recommend always starting seeds off in a sterile potting mix/seed compost which can be bought or made at home – Alys Fowler recommends a couple of minutes in the microwave or popping it in the oven for an hour at 80C/175F – the toaster oven would work for that.

Any other suggestions for Joel – how he could pass it on or reuse/recycle it for other purposes?

Good friend (and bully ;) ) of Recycle This and The Really Good Life Su has emailed with a question:

Me again! With an actual, proper reuse question!

My much used enamelled, cast iron casserole dish has died. Proper died, a large section of the enamel has come off the bottom & I dropped the lid on the stone flagged kitchen floor & it broke into 3 pieces!

Me & that casserole have been together a long while & been through many culinary adventures, I know that I could put a plant in it, but wondered if you or anybody else had any idea how I might reuse it?

You might be able to get a replacement lid – I see branded ones popping up on eBay regularly – but I suspect the enamel coming off is the bigger issue. There seem to be a few enamel repair products for chips on ranges or stoves but which wouldn’t be suitable for cookware. Some people on Chowhound recommend continuing to use it if it’s not flaking – the cast iron will eventually season like non-enamelled cast iron – but I could understand other people being unwilling to risk contamination.

Away from cooking, unfortunately the wear to the enamel would stop it being useful as a small dye bath or a soap making pot since the newly exposed iron would react with the dye or raw soap. (The latter is a particular shame as the heavy iron would be useful to help maintain the desired temperature during hot process soap making.)

I can completely understand Su’s desire to keep it around – it’s one of those things that seems like it would be really useful – but I’ll admit to being at a bit of a loss about what I’d do with it, other than for storage (a fun fruit bowl? or for craft bits or knick knacks?) or the planter than Su mentioned.

What would you do with it? How would you reuse or recycle it?

Bee has asked:

What can I do with a lot of wood ash after it has been leached? I have a large firepit, and I plan on saving and leaching the ashes… but I’m very leery about tossing that much slag ash onto the compost heap. I’ve found lots of info about ashes before leaching, but practically nothing about after leaching.

Funnily enough, I was riddling our woodburner and thinking about recycling ash just before I spotted this question from Bee :)

We’ve already covered the various different ways to reuse wood ash – from unpainted/unvarnished wood – in the garden and beyond — and one of those ways is to use it to make lye, which is what Bee is talking about here: the wood ash left after it’s been steeped to make lye for soapmaking or what-have-you.

I haven’t made lye myself – we just compost the ash – and like Bee, my Google-fu has failed me. I can find lots of tutorials on how-to make lye from wood ash but they all just skip from making the lye solution to using the lye, without explaining the clean up.

So does anyone know if the leftover ash is suitable for composting? I suspect it would be fine to go on a well-balanced compost heap – when “raw” wood ash is composted, the lye & salts leach away into the compost over time and the resulting compost will be alkaline but not too caustic to burn plants. The leaching process will have removed a lot of the lye so in theory it shouldn’t damage your heap – although equally, there is less point in it being there because it contains less minerals than “raw” wood ash – better than being thrown into landfill but not going to add a lot of goodies to the garden. That’s what I think anyway, from looking at the situation now — I am very happy to be contradicted by someone who has had experience of composting it.

Is there anything else that can be done with it? What would our ancestors – who wasted so very little – have done with it?

We’ve had an email from Mark:

What is the best way to recycle small quantities of hot water from a condenser tumble dryer?

I know i could pour it down the toilet, put it on the garden etc, but what are the economical benefits of reusing this clean water. Can it be used (when cold) for anything beneficial? Recycled/redirected to a dishwasher etc

In yet another of those great-minds moments on here, I’ve been thinking a similar thing lately – we’ve had a dehumidifier running in our office after a series of leaks over the summer and while it’s thankfully slowed down a lot of late, we’ve had bucket upon bucket of water from it over the last few months. For me it’s less about the “economical benefits” and more about hating throwing anything away that might be useful.

Wikipedia describes this type of water as “a rather clean kind of greywater” – but various articles online advise against drinking it/letting animals drink it (because of possible bacterial/fungal spore/heavy metals contamination, and also because it’s been distilled & will taste weird). Watering well-established houseplants with it is probably ok – actually better than tap water if you’re tap water is very soft – although because of the possible bacterial/heavy metals issue, it’s still probably better to avoid using it on vegetables, particularly leafy ones.

Mark mentioned putting it down the toilet – I’m not sure whether he means just to get rid of it or in lieu of flushing. The latter will have an “economical benefit” if your water is metered — toilet flushing accounts for a huge proportion of most people’s water usage: just keep a bucket of water next to the toilet and pour some into the bowl to flush it. I’m not a water expert but based on the advice about possible contamination, I’d probably be more inclined to use it for clothes washing than dish washing (although it would probably be fine for that too, especially at hotter cycles).

Anyone have any experience reusing water from condenser dryers, air con units or dehumidifiers? What do you use greywater for around your home/garden?
