Chris - your message came in while I was attempting this. It's actually an upright. ( D..n it - I've got to re-invent what I said!!)
OK, Natty - would you accept greaseproof paper? Do you ever put wax discs on your jams - for a similar but different purpose?
Believe me, with an environmental guru for a son, we think along the same lines. I accept that you are happy but, for all those who might not be, I have to say that sealing the surface of the food makes one hell of a difference to the quality of the end result. And that's even using purpose designed plastic boxes. Much depends, of course, on how long one stores things. I'm afraid that, despite great effort to rotate goods within their bbe dates, I am guilty of missing out on something each year. The children 'go off' things that you have so diligently prepared. And that, of course, is more environmentally unsound than the covering?? Wasting fuel?
Equally so, but to some extent in my defence, we do have an 18cuft & a regular freezer & a good larder, making good discipline a constant requirement.
And we're talking about feeding 7 at least once a week & up to 14 not infrequently!!
I'll redouble my efforts!!
