Lemon Coleslaw

My favorite coleslaw from the Gourmet Cookbook (2005)

Lemon Coleslaw

2 T sour cream
2 t mayo
1/2 t finely grated lemon zest
2 T fresh lemon juice
3 T water
1 t sugar
1/4 t salt (or to taste)
1/8 t freshly ground black pepper (or to taste)
4 c (or approximately 1 lb) thinly sliced green cabbage  I just buy a bag of coleslaw
2 carrots coarsely grated
1 c thinly sliced green onions/scallions (1 bunch)
1/2 c chopped cilantro

Whisk together sour cream, mayo, zest, juice, water, sugar, salt and pepper in a large bowl until sugar is dissolved. Add cabbage, carrots, scallions and cilantro and toss well. Refirgerate, covered for 1 hour to allow flavors to develop.
