1. Wash and dry the oranges and lemon. Quarter them and remove seeds and thick membranes (but do not peel). Put through a food chopper, using the coarse blade. Peel and pit the peaches and mash slightly with a pastry blender or fork.

2. Place all the ingredients except the pecans in a large kettle over medium heat. Bring to a boil to dissolve sugar, stirring occasionally. Reduce heat to low and simmer for 1 1/2 to 2 hours, until mixture measures 221 degrees on a candy thermometer or falls in sheets from a spoon. Stir occasionally to prevent sticking, and crush any large pieces of peach.

3. Remove from heat and stir in the pecans. Carefully ladle conserve into hot, sterilized jars, leaving 1/4-inch head space. Wipe excess conserve from inside and outside rims, then seal.
