Crab sticks and crab cakes

Crab sticks (also known as seafood sticks) actually have nothing to do with crab. They are made of white fish such as Pollock, egg white, pulverized into a thick paste before adding red colour.  I have no problem with the name 'seafood sticks', but they should not be called 'crab' sticks.

Crab cakes, on the other hand, usually contain at least 20% real crab meat, depending on the recipe. For example, Sainsbury's Taste the Difference crab cakes contain 25% crab meat.

Loose fruits and veg are cheaper

Asda charges 68p a kilo for loose bananas and £1.40 for a pack of ten. Although many customers believed the pack would be cheaper, buying ten loose bananas cost £1.20 – a saving of 20p.

At Sainsbury's, there are eight fruit in a £1.15 pack of 'Fairtrade Basics' bananas. Buying the same number loose would cost 96p – a saving of 19p.

Tesco sells an 'Eat Me' pack of five bananas for £1, while buying loose fruit would be 40p cheaper at 60p.

In Waitrose a pack of six 'Essential Fairtrade' bananas was £1.38, while buying six loose would cost 72p.

A Which? spokesman said: Supermarkets make it impossible to work out whether it's cheaper to buy bagged or loose fruit. We want them to show clear unit pricing – price per weight or item – so you can compare.

"Big four" supermarkets in UK

Asda is generally the cheapest (an average of about 3%), followed by Tesco, then Morrisons and Sainsbury's.

The difference between mild, medium, and mature Cheddar cheese

The difference between mild, medium, and mature Cheddar cheese is their age.
Mild Cheddar - about 3 months of age
medium Cheddar - about 5 to 6 months
mature Cheddar - around 9 months
extra Mature - around 15 months
Vintage cheddar- 18 months to 2 years

As Cheddar matures so it's taste develops from the young creamy taste of mild Cheddar to complex, lasting, slightly nutty flavours of mature Cheddar and beyond. These more mature (extra mature or vintage) Cheddars tend to have a characteristic sweet, nutty flavour.
