Even the ones from M&S?
Good grief woman, just because you pay over the top for their veg doesn’t mean it’s better!!! Go to Lidl or Aldi. I guarantee it will last the same, taste the same and do everything M&S veg do.
Don’t you realise that the majority of people are not admiring your using that shop for veg, but amused at your pretentiousness in thinking it is automatically better as well as being so expensive. I only ever buy English tomatoes. Im fussy about which types and believe me, Aldi, Tesco and Lidl have a much better,tastier selection than zM&S.
As to blanching, never bother. All left over veg gets chopped up and bunged in freezer. Except onions. They get sliced, popped in microwave on high for a couple of minutes and fried before being popped into small bags ready for use. No. Not in air fryer.
Unless you want onion crispies of course
Great to pop into a packet of crisps.
