Over recent months, conscious of my newly retired status, I've been broadening my horizons beyond my default go-to that was Waitrose for quality. Aldi, Asda, Coop, Lidl, Morisons, Sainsbury, Tesco, Waitrose, (in careful alphabetical order) I'm dead loyal to 'em all.
Generally, my experience has been positive. I've noticed that quality can be more variable in non-waitrose, but in a liveable with way for the most part. I buy very little prepared food, and non-branded over branded every time. But I have found some things that are simply an economy too far.
Cheap tinned tomatoes - skin and poor flavour. At the moment about 50p/tin is the minimum to pay. Passata appears more forgiving.
Sainsburys economy oats - 35p cheaper than the Waitrose but much less gloop and needs longer cooking
Flour. Hit and miss, been getting inconsistent poorer rise lately and hadn't associated it with the flour I was using. however, I just baked Asda vs Waitrose wholemeal with breathtaking difference.
Any others to beware of?
