Use quality canned butter beans like Jack’s Butter Beans for best texture. Drain and rinse to remove excess salt and liquid., Stick to full-fat coconut milk to achieve rich, creamy texture; if too runny, simmer uncovered or mash some beans to thicken., To thicken without mashing, stir in a slurry made from 1 tsp cornstarch or arrowroot mixed with 1 tbsp cold water and simmer for 1 minute., Add garlic towards the end of sautéing onions to avoid burning; toast turmeric and smoked paprika briefly to bloom flavors., Season gradually with salt and brighten the dish with lemon or lime juice at the end for best flavor., Avoid overcooking to keep beans tender but intact., Store in an airtight container in the refrigerator for up to 7 days or freeze for up to 3 months., Reheat gently on stovetop or microwave; add a splash of water, broth, or coconut milk if the sauce is too thick or dry., Flavors improve after resting overnight—make-ahead and enjoy leftovers.
