I Rate My Jams

I have been wondering how to rate my jams - the 11 jars plus one of blackcurrant I received from my Longest Serving Friend for my birthday. Five jars in, and I'm in danger of losing the plot. I haven't been sure how to do the rating - I've been mulling over categories such as 'Jamminess', 'Blackcurrantiness', 'Jamminess' ... and generally going around in circles. 

Inspired by marking some assignments, I have decided to use categories I'm used to - ones which are used to judge essays. The four categories are:

Presentation - How's the look of the thing, the grammatical integrity of its label?

Structure - how do the blackcurrants sit together? Is there a sense of flow and logic?

Content - How relevant is the jam to the question set?

Knowledge and understanding - Does the jam understand what it's trying to do?

The table below is a work in progress. I'm five jars in, seven blissful more jars to go.

 

Type	Presentation	Structure	Content	Knowledge and Understanding
St Dalfour	Slim and elegant	Untested
Hartley’s	Predictable and shapely	Loose – random placement of blackcurrants in a thick enough syrup.	Blackcurrant-lite compared to the others but maybe not compared with budget versions which my LSF didn't consider birthday material	This jam does not understand that it’s a jam. It thinks it’s a form of entertainment
Fortnum and Mason	Conservative and purposeful	A dense, thick jam. More of a spread, with its own definition of integrity	Blackcurrant-superior-and-don’t-you-know-it	This jam, whilst rich and privileged, lacks self-awareness. It approaches toast as if it is triangular and crustless
Wilkin & Sons Ltd	Traditional yet stylish	A delightful texture which accommodates to any surface: toast, bread, spoon, tongue	Blackcurrant-just-right.	The baby bear of blackcurrant jams. This jam can do no wrong, but it is risk-averse.
Meridian	worthy and lower case	Untested
Sainsbury’s Taste the Difference	Get your act together, Sainsbury’s	Somehow, the blackcurrants are whole and plump	Tart and sweet. Best of both.	This jam has the maturity to know when to lay it on thick. Every spoonful is a coming of age.
Streamline	Oh pl-eeease! Streamline! I like the lid, though.	Untested
Waitrose	You know how I feel about Waitrose	Untested
Waitrose Duchy Organic	Jam is a classist issue	Untested
M & S	Come on M&S. Get in a new graphic designer. Maybe my friend Pixie.	Untested
Bonne Maman	Perfect. Does what it says on the jar. But what about Bon Papa?	Untested
Goetre Farm	Perfectly acceptable home-made appearance	Perfectly acceptable home-made structure	Perfectly acceptable  home-made content	Perfectly acceptable  home-made understanding of jam
