Southwestern Pineapple Sauce pairs fire-roasted poblanos with a whole can of pineapple — the peppers get blackened over an open flame like marshmallows, peeled, then simmered with the pineapple purée until everything melts into one smoky-sweet, mildly spicy sauce. It makes about two cups, keeps for weeks chilled, and earns its spot next to Fool's Gold Chicken Nuggets, carrots, and grilled fish.
Pro Tips
- Roast the poblanos over an open burner flame or under the broiler, turning every few minutes, until the skin is blackened on all sides — the char is the smoky backbone of the sauce.
- Once the peppers come off the heat, cover them airtight and wait at least fifteen minutes; the trapped steam is what loosens the skin so it peels instead of tearing. Run stubborn spots under water.
- Purée the peeled peppers with the pineapple and its juice together — canning liquid and all — so nothing sweet is left behind in the can.
- Watch the garlic in the oil: it needs about four minutes to reach just-starting-to-brown, and garlic that goes past brown turns the whole pot bitter.
- Simmer the full twenty minutes, stirring now and then, until the purée reduces to a thick sauce; serve it cold, straight from the fridge.
Frequently Asked Questions
How spicy is Southwestern Pineapple Sauce?
Mild — poblanos carry more smokiness than heat, and the pineapple rounds out what warmth they do have. Kids who tolerate a little warmth generally like it.
Can I use fresh pineapple instead of canned?
Yes — one whole pineapple replaces the 20-ounce can. Purée the flesh with its juice, exactly as you would the canned chunks.
How long does the sauce keep?
Stored chilled in a sealed container it holds for several weeks, thanks to the vinegar and the long simmer.
What should I serve with pineapple sauce?
It's built as a dip for Fool's Gold Chicken Nuggets, carrots, and cauliflower, and it's equally good spooned over fish or roasted vegetables.
