In a saucepan or pot over medium heat, heat the canola oil and sauté the onions and garlic until the onions are translucent (approximately 3 to 4 minutes).

Add the apples and continue to sauté, stirring often, for 5 minutes.

Add the habanero peppers, water, apple cider vinegar, sugar, and salt. Stir well and allow the mix to simmer, stirring occasionally, until the apples soften (approximately 15 to 20 minutes).

Remove the sauce from the heat and pour it into a blender (or use an immersion blender if using a pot). Add the additional 2 cups of water and blend the sauce until smooth. Add additional salt to taste.

Use immediately, or for best flavor refrigerate the sauce for 2 to 3 hours at minimum to allow the flavors to meld.
