Paste
1/4 Cup fresh ginger, shredded
1/4 Cup shallots
4 garlic cloves
1 serrano chili pepper, sliced, stem removed
1/3 Cup olive oil
12 boneless, skinless chicken thighs cut into strips
1/2 tsp kosher salt
1/4 tsp cayenne pepper
1.25 Cups coconut milk
1/2 Cup natural peanut butter
2 TB lime juice
1 TB fish sauce
1/4 tsp fresh ground black pepper
In a food processor (or old school with a mortar and pestle) blend together the ginger, shallots, garlic, and chili pepper, adding the oil slowly to create a paste. Set aside half the paste in a saucepan. Put the other half in a big plastic bag with the chicken strips, salt, and cayenne pepper. Seal it tight, mush it around to coat thoroughly, then refrigerate for 1 hour.
Heat the saucepan with the other half of the paste to med-high on the stove. Cook for 3-4 mins, stirring often. Add the remaining ingredients, whisk until smooth, and simmer until it reaches a creamy consistency (2-3 mins).
Thread the chicken strips on to skewers. Grill over direct high heat until fully cooked, turning once (about 5-7 mins). Serve with the warm sauce.
