Cut the baked sweet potatoes in half, scoop out the soft pulp, and discard the skins. Mash the sweet potato pulp using a potato masher, food mill, or potato ricer until smooth.
Add the 1 tsp (0. 17 oz / 5g) of salt, 0. 5 tsp (0. 05 oz / 1. 5g) of turmeric, 0. 25 tsp (0. 02 oz / 0. 7g) of paprika, 0. 25 tsp (0. 02 oz / 0. 6g) of ground nutmeg, 4 tbsp (2 oz / 60g) of orange juice, and 0. 5 tsp (0. 03 oz / 1g) of orange zest into the bowl, whisking vigorously with a fork until the mixture is thoroughly blended and uniform in color.
Place a 12-inch (30 cm) frying pan over moderate heat and melt the 3 tbsp (1. 5 oz / 42g) of ghee or butter.
Once the ghee is hot, sprinkle in the 1. 5 tbsp (0. 6 oz / 18g) of brown sugar and cook, stirring frequently, until the sugar caramelizes into a deep reddish-brown color. Immediately drop in the 12 oz (340g) of chopped Italian plum tomatoes and gently toss them in the caramelized ghee for 1 to 2 minutes, just until they begin to soften and take on a glossy shine.
Transfer the spiced sweet potato mixture into the frying pan with the tomatoes.
Using the back of a sturdy wooden spoon, firmly mash and fold the ingredients together, ensuring the tomatoes and caramelized ghee are evenly distributed throughout the purée.
Cook for an additional 3 to 4 minutes until the mixture is completely warmed through, then transfer to a heated serving platter and garnish evenly with the 2 tbsp (0. 5 oz / 15g) of toasted sliced almonds before serving.
Roast, Don't Boil: To achieve the deepest flavor and prevent a watery mash, always oven-bake (or ash-bake, if you have a wood fire!) your sweet potatoes.
Boiling introduces excess moisture that dilutes the natural sugars and spices.
