Full rankings and ratings
Morrisons' Original Porridge (55p for 55g) came last with a 4/10 rating, described as overly sweet and lacking creaminess, with 12.2g of sugar.
Lidl's Crownfield Instant Oats (37p for 50g) scored 5/10, similar consistency but lower sugar at 5.9g, requiring added honey.
Asda's original (8.2g sugar) rated 6/10, thick but bland with an unpleasant aftertaste, improved by honey.
Aldi's Golden Bridge Original Porridge (37p for 50g) achieved 7/10, thicker with a more natural flavour, though still slightly watery. At 6.4g sugar, it needed honey. Davies called it "an excellent budget choice".
Sainsbury's Original Porridge (65p for 50g) scored 7.5/10, thick and inviting texture, plain but transformed by honey into a contender for first place.
Top three
Quaker Original (£1.30 for 45g from Morrisons) ranked third with 8/10, producing thick, creamy porridge with 5.3g sugar, but cost weighed it down.
Tesco's Instant Oats Original (41p for 55g) came second with 8.5/10, impressively thick, creamy, and lightly sweet with 9g sugar. Davies added no honey, finding it surpassed Quaker on cost.
M&S' Traditional Porridge (£1 for 70g) won with 9/10. It was beautifully thick, creamy, and satisfying without honey despite only 4.1g sugar. Davies said "on taste alone, it was the undisputed champion", with a consistency like creamy rice pudding.
The taste test follows Which? naming Aldi the UK's cheapest supermarket for a basket of 95 groceries at £163.34, with Lidl at £164.92.
