Heat a dry medium saucepan over medium-high heat, then add the ground pork and stir occasionally, breaking into bite-size pieces, until the pork has browned (about 6-8 minutes).
Do not drain the oil (even though it looks like a lot)! Add the garlic and shallot, then stir occasionally until softened, about 2-3 minutes.
Stir in the chicken stock, cherry tomatoes, peanuts, tamarind, miso, harissa, tomato paste, and sugar. Stir in the lime juice and season to taste with the kosher salt (you shouldn't need much - maybe ½ - 1 teaspoon).
Turn the heat down to low, then simmer, uncovered, until the ragu thickens considerably, about 30-40 minutes. Check the seasoning and adjust if necessary (with more lime juice, sugar, salt, or spice (in the form of harissa paste or chili flakes)). Serve immediately, over pasta, rice, roasted vegetables, zucchini noodles, freshly cooked corn, hearty baby greens (like kale and arugula) or with bread alongside for scooping the sauce up.
