If you really need plum ideas...
Rachel Henderson
We're happy to finally have a plum harvest this year. We've been picking our favorite variety -- Black Ice, developed at UW Rive Falls -- for a week or so, and are starting on LaCrescent, a small yellow variety. We should have a couple more to bring to market before the season ends. Mostly, these plums just get eaten up in our house, but here's a link to a few awesome recipes, should you really need one.
