Crockpot Lamb with Mint

Lamb with mint is a classic combination so I thought I'd try it in the crockpot.  I made a mistake on this by add the mint at the beginning of the cooking time.  It tasted fine, but it wasn't minty at all.  Lamb in the crockpot is so much better since it's easy to keep it from drying out.  I used a Sneaky Chef puree in this.  I'll definitely try this again adding the mint at the end.

1 1/2-2 lbs lamb shank
1/4 cup Green Puree
1/2 cup white wine
2-3 cloves garlic, chopped
2 cups fresh mint leaves, chopped in food processor

Place lamb in the crockpot.  Add Green Puree and garlic.  Pour in white wine.  Cook on low for 7-9 hours.  Add mint 15 minutes before serving.
