I bought some of those Home Bargain jars, and they are good, (Eerin is the name on them) but I found I needed to be careful with the rings. Some of the ones I bought aren't interchangeable with the Kilner ones and kind of birl round on the jar instead of tightening up to 'finger tight'.
I kept the two kinds separate for a bit. In the end it was just a bother and I put them away. If anyone who lives near me wants a box load of the Eerin ones, let me know and I'll dig them out of the shed for you. There's absolutely nothing wrong with them, just that I don't mix the two kinds now.
Having said that, I was very disappointed in the quality of some of the latest Kilner jars I bought. No longer made in the UK but made in China, and they were not even, the glass was thick and thin.....how hard can it be ? we spend a lot of money buying these jars, yet the folks who make and sell pasta sauces and the like need a consistent quality, and they get it, and mostly folks just throw those jars away, yet they were more consistently even walled than the ones I bought.
My son's girlfriend is Italian, she says they don't throw them away, but they are washed and stored and used again to store red sauces when there's a glut of tomatoes and peppers in Summer and Autumn, and they've been doing that since before the war. It's a known technique and doesn't need any further expense.
Much I suspect like us making jam here, yet I watched a youtube video of an almost screaming American lady insisting that people die in the UK from doing this
I jest you not, she insisted that by not 'canning' our jams that we were dieing in the hundreds of botulism.
Complete idiot, and utterly false. The only cases of botulism in the UK were from meat, and it wasn't from meat grown or processed here, and instead of the hundreds, there were five.
