for 45 minutes to 1 hour, or until the apricots are soft. Transfer the apricots and the cooking liquid to a food processor and puree until smooth. Return to the saucepan, along with honey and the remaining quarter cup lemon juice. Simmer, stirring often, until very thick, about 1 hour. Stir in crystallized ginger and let cool. (The butter can be stored, covered, in the refrigerator for up to 2 weeks or in the freezer for up to 6 months.)
