Wear gloves to handle ghost peppers. Remove stems and roughly chop peppers. Dice pineapple and pears, peel and mince garlic, and finely chop onion.
n a large saucepan, combine pineapple, pears, ghost peppers, onion, garlic, white vinegar, apple cider vinegar, and water. Bring to a boil over medium-high heat, then reduce to a simmer.
Cook for 15-20 minutes, stirring occasionally, until fruits and peppers soften and flavors meld.
Stir in sugar, salt, ginger, and turmeric. Simmer for an additional 5 minutes until sugar dissolves.
Remove from heat and let cool slightly. Blend mixture in a blender or food processor until smooth. For a smoother texture, pass through a fine mesh strainer.
Pour hot sauce into sterilized glass bottles or jars, leaving 1/4-inch headspace. Seal tightly.
Let cool to room temperature. Refrigerate for at least 24 hours before use to allow flavors to develop. Store in the refrigerator for up to 3 months.
