Firstly, bring a large saucepan to medium-high heat. Add olive oil, diced onion, garlic, ginger, stock powder, turmeric, black pepper, crushed chilies, rosemary and bay leaves. Sauté for 5mins or until the onions have become translucent and the spices have started to brown.
Add the beef mince and vigorously mix the raw mince with the onion mixture to ensure that the mince doesn't clump up together. Sauté for 8-10mins or until the beef has started to brown.
Add 2 liters of warm/boiling water, potatoes, pumpkin, and red or white wine vinegar to the mince and bring to a boil, then drop the heat to medium. Simmer uncovered until the potatoes are tender.
Once the vegetables are tender, turn the heat to low. Remove the bay leaves and add the miso paste and stir well. Note: I add some of the stew liquid to the miso paste to loosen it up before adding it to the stew. Also, dilute the cornstarch in 2 tbsp room temperature water and add it to the stew. Allow to simmer on low heat for 5mins. Remove from the heat and salt to your taste but take note, miso paste has quite a high salt content. Note: if you'd like the stew to be thicker then lightly break some of the vegetables to add more body.
Allow to rest while you prepare your serving bowls, toasties and butter. Enjoy, Tastebud!
