But it is also finding that the jar of jam in the back of the fridge, unopened since last summer, is not amelanchier, as you had supposed - good in its own way, but better for pies - but the red currant, black currant and raspberry jam made from berries bought at some cost at the Union Square farmers' market last summer.

To discover this one May later, is a happy, happy thing.
