There's been a lot of good things said about Clippy's Apples preserves in particular their conserves.  After all there are not many apple jams around really so they are a bit of a novelty.  

Jam. Glorious, glorious jam.

Rich ruby red or berry blue, smeared on scones and faces and fingers. Scooped from the jar with a silver spoon. An instant taste of endless summers, long lazy days when the sun shone and the skies were always blue.

Topped with cream, filling sandwiches of white crusty bread, a jewel waiting to be discovered in a comforting bowl of milky rice pudding.

Strawberry, raspberry, blueberry, fig. Cherry, blackberry, rhubarb and plum. Every one a favorite, a treat, a smile, a hug...
