I found this recipe in a magazine Years ago. Food and Wine I think. Anyway, it's always a hit.

Grilled Shrimp with Orange Curry Peanut Sauce

1/3 C orange marmalade
¼ C orange juice
2 T creamy peanut buter
1 T Dijon mustard
1 T curry powder
1 tsp vegetable oil
½ tsp salt
½ tsp crushed red pepper flakes
¼ tsp chili garlic paste such as Sambal Oelek
Zest of one orange

Combine all ingredients. Taste and adjust seasonings to taste. Baste over shrimp and grill. Also works with chicken or pork. Serve more sauce on the side.
