Canola oil, for frying
2 lbs. chicken wings, separated into 2 pieces
4 tbsp. unsalted butter
3 canned chipotles in adobo and 1 tbsp. adobo sauce, puréed
2 tbsp. fresh lime juice
1. Heat oven to 200˚. Pour oil into a 6-qt. Dutch oven to a depth of 2" and heat over medium-high heat until a deep-fry thermometer registers 400˚. Working in two batches, add chicken wings to oil and cook, stirring occasionally, until golden brown and crisp, 10–12 minutes. Using a slotted spoon, transfer wings to a wire rack set over a rimmed baking sheet and transfer to oven.
2. Meanwhile, put butter and chipotles into a medium heat-proof bowl. Set bowl over a pot of boiling water until butter is melted and chipotles are hot, whisking to combine. Transfer chicken wings to the bowl, add lime juice, and toss to combine.
