1. In a medium stainless-steel saucepan, combine the wine, water, sugar, and star anise and bring to a simmer over moderately high heat.
2. Add the plums. Bring the poaching liquid back to a simmer and cook, partially covered, until the plums are just tender, 10 to 15 minutes. Pour the plums and their liquid into a glass or stainless-steel bowl and let cool. Stir in the lemon juice.
Variations : You can use red wine instead of white.: Add several strips of orange zest to the saucepan along with the star anise.
