First, gather all your ingredients and utensils. That makes it so much easier and more fun and you're less likely to forget anything.
Sauté onions and ginger in plant oil in a medium pot that has a lid at medium to high heat for two minutes, then add garlic and curry powder. Stir well for about 30 seconds.
Add pumpkin and stir again.
Then add coconut milk, water, veggie broth, peanut butter, ketjap manis and sambal oelek. Stir very well again, you want to make sure the peanut butter is properly dissolved. Then bring to a boil and simmer for 15 minutes at medium temperature with the lid slightly ajar. Stir from time to time.
Wash and dry cilantro, then chop the leaves. I like to use a salad spinner.
When the curry is ready, stir well again and taste if the pumpkin is buttery soft. If not, it needs to simmer a little longer.
