OK, that might be overstating things: more my final posting on this topic for a while. I hope that there is infinite innovation on (eco) food storage in my future.
I have been using glassware to store my food for about 15 years. Glass containers used to be hard to come by, but now they are everywhere.
Glass has so many advantages: it is inert, so no nasty leaching; it goes in the dishwasher, no problem; it can go in the oven as well as the freezer; and it does not stain or retain flavours. The only downsides are that it breaks (of course), though do bear in mind that unless you buy the very cheapest containers you will be purchasing borosilicate glass, which is far more robust that regular glass. Having said that, I really only use glass for in-home storage, partly because it is quite heavy (I did try the lunch bag thing once…not again).
The French were ahead of us all on tempered glass (think about those Duralex glasses that I like so much), or maybe they were just the first who discovered how to make lids.
My oldest glass containers are from Luminarc. I bought them in the UK around 1998 and they are still going strong, though the lids are somewhat split at the edges (I do not always observe the `top rack only’ instruction when it comes to my dishwasher, but since I always wash on the delicate setting to save energy, I figure I get a break).
But now everyone from the dollar store up seems to be making glass with lids (it is the lids which are key to food storage, of course).
As noted, the cheaper the glass the less robust it seems to be (in my experience). It is also not clear to me what the plastic lids on the cheap containers are made from. There is little point in moving to glass if you are going to cover your food with an off-gassing, BPA-laden lid.
I have, as is my wont, tried most of the glass containers on the market today. I like the idea of the Glasslock type with the flaps that snap shut and make things water- and air-tight. But I don’t like them in practice. You seldom need this degree of seal and I find it hard to get them to close completely. You are also limited to rectangular or square shapes …. I have a soft spot for circles.
My new favourite glassware comes from no further away than the US (yes, the glass itself is actually made there, though the lids do, I am afraid, come from China).
The TrueSeal range from Anchor has flexible (possibly partly silicone?) BPA-free lids with a see-through panel in the top to help you see what is inside. The lids are super-easy to put on and seem to last well. The manufacturer claims that by pushing down the lid to squeeze out air you can make things pretty water-tight. There are differing views on this in web reviews, but I put water in one of mine and turned it upside down and the seal did indeed seem to be true.
The range includes round containers (which nest) as well as square, loaf-shaped and taller containers.
They are all microwave, dishwasher, oven and freezer safe. And since I have a soft spot for lime green (did anyone guess that ?), I like the way these look in my kitchen. They are also fine for serving which cannot be said for plastic.
In the US TrueSeal glassware is available most everywhere, it seems (so Target, Walmart, etc.) and is good value at $25 for a 10 piece set (5 round containers with lids) at Walmart online. I am not sure whether Walmart stocks the TrueSeal range in Canada (I guess I should visit and check it out but I can’t quite bring myself to do that, even for you, dear readers).
I bought the ones I have in a larger Loblaws store, but they certainly don’t sell them in my local Loblaws. I found a better selection at Canadian Tire. Of course they are more expensive here in Canada, around $6 to $12 per container or $19.99 for a set of 3 round containers with lids.
