Start your rice in the rice cooker
In a large pot or deep pan, heat oil over medium heat. Add in minced shallot, grated ginger, and minced garlic. Sauté for 2-3 minutes.
Add curry paste and let it "bloom" in the oil and stir well . Cook for 2 minutes, then add in sliced bell pepper and cubed pumpkin. Stir and continue cooking for 2 more minutes.
Add in coconut milk, brown sugar, and salt, and stir. Bring mixture to a simmer. If using a protein, add it in at this point. Cover with a lid and lower heat to medium-low to continue simmering for 20 minutes.
To make the curry thick and creamy, take about half of the coconut milk and cooked pumpkin (leave the protein in the pot if using) a food processor until completely pureed, then add back into the pot.
Add in fish sauce at the last minute, stirring occasionally.
Serve with steamed rice and top with fresh herbs like cilantro.
