Combine ginger ale, honey, lemon zest and ginger in deep saucepan.
Bring to a boil.
Meanwhile, peel 3/4 of each whole pear and do not remove stem.
Place pears into ginger ale mixture, lower heat, cover and simmer until almost tender (about 15-20 minutes).
Turn pears to ensure even cooking.
Once pears are cooked, remove from ginger ale mixture.
Reduce mixture down to 3/4 cup.
Heat mixture on high.
Once heated, strain over pears and allow to cool.
Place each pear in a shallow soup bowl and wrap a slice of lemon around the stem, tuck a mint leaf into the lemon slice and sprinkle with nutmeg.
Drizzle with sour cream.
