America's Test Kitchen build this chilli around a homemade powder ground from six toasted dried ancho chillies, tortilla chips and a custom spice blend. The beef mince is treated with water, salt and baking soda before searing, which holds its moisture and helps it brown despite a crowded pan. Their original is finished in a 275F oven for one and a half to two hours. It translates well to a slow cooker because that long, low braise is exactly what the slow cooker is built for. The hob work stays (toasting the chillies, browning the beef and blooming the spices is where the flavour lives), then it all goes into the slow cooker for the unattended cook.
Slow cooker notes: Original is a hob simmer transferred to a covered 275F oven for 1.5 to 2 hours. Adapted to a slow cooker by keeping every hob step that builds flavour (toasting the dried chillies, grinding the homemade chilli powder, the baking soda rest on the beef, browning the beef, blooming the spice mixture in the rendered fat, adding tomatoes) and then moving the lot to the slow cooker for the long braise. Low 6 hours or High 3 hours gives the same tender, broken down beef mince the source describes. Cider vinegar and a final salt seasoning go in at the end as the source instructs. Do not skim the fat layer that forms (the spices are oil soluble, per the source).

Method
Prep the dried anchos. Tear off the stems and rip the chillies open, shaking out most of the seeds. Tear the flesh into pieces about 2.5 to 4 cm across.
~5 minToast the chillies in a dry pot or large pan over medium-high heat for 4 to 6 minutes, until you can smell them. Pull the pot off the heat the moment it starts to smoke. Tip the toasted chillies into a food processor and let them cool until crisp.
~6 minTreat the beef. In a bowl, dissolve 1.5 teaspoons of salt and 0.75 teaspoon of bicarbonate of soda in 2 tablespoons of water. Add the 900g of beef mince and toss to coat evenly. Let it sit on the counter for about 20 minutes.
~20 minGrind the chilli powder. To the cooled chillies in the food processor, add 28g of tortilla chips, 2 tablespoons ground cumin, 1 tablespoon ground paprika, 1 tablespoon garlic powder, 1 tablespoon ground coriander, 2 teaspoons dried oregano, 2 teaspoons ground black pepper and half a teaspoon of dried thyme. Process for about 2 minutes to a fine powder with no big chilli pieces left. Tip into a bowl.
~4 minProcess the tomatoes. Tip the 411g tin of whole peeled tomatoes and their juice into the food processor and pulse for about 30 seconds until smooth. Set aside.
~1 minBrown the beef. Put 1 tablespoon of vegetable oil in a large heavy pot over medium-high heat. While it heats, chop the onion. Add the chopped onion to the hot oil and cook for 4 to 6 minutes until softened. Stir in 3 minced garlic cloves and cook for about 1 minute until fragrant.
~8 minAdd the treated beef mince to the pot. Crowd the pan, the baking soda trick will brown it anyway. Break the meat up into small pieces with a spoon and cook for 12 to 14 minutes until well browned on the bottom and some of the fat has rendered.
~14 minBloom the spices. Add the homemade chilli powder and 2 teaspoons of finely chopped chipotles in adobo to the browned beef. Stir for 1 to 2 minutes in the rendered fat to bloom the oil soluble spices.
~2 minStir in 2 teaspoons of sugar and the processed tomatoes. Bring to a simmer.
~3 minTransfer everything from the pot to the slow cooker. Cover and cook on Low for 6 hours or High for 3 hours, until the beef is tender and the chilli has thickened.
~360 minLet the chilli stand uncovered for about 10 minutes to settle. A layer of fat will rise to the top. Do not skim it. Stir it back in, the spices are oil soluble and most of their flavour is in that fat.
~10 minStir in 2 tablespoons of cider vinegar. Taste and season with a little more salt as needed.
~1 minLadle into bowls. Top with chopped fresh coriander, minced red onion, shredded cheese, diced avocado, a dollop of soured cream and a spritz of lime.
