How to Make It
Heat olive oil in a Dutch oven over medium. Add shallot, and cook, stirring occasionally, 2 minutes. Add pears and lemon juice, and cook, stirring occasionally, until softened, about 5 minutes.
Add vinegar, raisins, brown sugar, ginger, salt, mustard seeds, cinnamon, nutmeg, and lemon zest; cook, stirring occasionally, until pears are softened, 20 to 25 minutes. Remove from heat. Fold in pine nuts.
Spoon pear mixture into 3 (1/2-pint) canning jars. Cool 15 minutes. Wipe jar rims. Cover at once with metal lids; screw on bands. Chill until ready to use. Chutney will keep up to 2 weeks in refrigerator.
