Pat roast dry and sprinkle with salt and pepper. Rub all over to evenly distribute.
Heat oil in a medium-high skillet. When oil is simmering add roast and sear on all sides. The best way to do this is to cook it on all sides for 4 minutes each to let it develop a good sear.
Place roast in crockpot and sprinkle with cumin and cinnamon. Add water to cover bottom of crockpot.
Turn on crock-pot on low and let cook for at least 8 hours. Can cook 4 hours on high. Pork is done when it cuts easily.
Dice apple and onion into similarly sized pieces. You can peel the apple if you would like but I never bother. Mince rosemary if using fresh.
Add 1 Tbsp of olive oil (or your preferred cooking oil) to the skillet. Once the oil is hot add the onions, apples and rosemary and let cook for about 10 minutes or until apples have softened. If your apples are not softening quick enough you can cover the skillet with a lid and allow them to steam for a few minutes.
Once the apple and onion mixture is cooked transfer it to a blender or food processor. Be sure to leave the hole in the lid open so the heat doesn't make it explode! Add 2 Tbsp of water and blend until smooth. Add more water if you would like a thinner consistency.
Serve pork with apple sauce drizzled over the top and enjoy!
Be sure that you are using pork loin and not pork tenderloin. They are two different cuts of meat that are not cooked the same!
