Perfect Peanut Sauce

From Cooking with Amy.
Ingredients:
1/4 cup peanut butter (natural, no sugar added kind)
2 teaspoons soy sauce
1 Tablespoon brown sugar
1 Tablespoon lemon or lime juice
1/4 cup coconut milk (lite is fine)
1/4-1/2 cup water
red chili flake to taste
chili garlic sauce to taste or 1 clove crushed garlic

Combine all ingredients with a whisk in a small bowl, adding the water last. Pour into a small saucepan and heat over medium heat until sauce begins to bubble and thicken. If desired, add a bit more water (around 1/4 cup) to thin the sauce out a bit. Good on noodles or as a dipping sauce for spring rolls.
