Good deal. Thank you.
Freeze it in an ice cube tray so it's portioned. Then just defrost when needed or if doing mash throw it in frozen..
I've bought these many times... frozen one used one. Why do people panic about dates, these have been useable 3 weeks or more past the date. Using one now and no I'll effects. I've picked the mould off crumpets and used the out of date butter....and no deaths reported!!
If the best before was pretty key then it would be a "use by" date to inform you it must be used by that date, best before is simply informing you exactly that, it's at its best before that date but could potentially be OK for a long time after so just use your eyes and nose!
Look at you Lad, spreading again (highfive)
