Chop finely lemongrass, garlic, ginger, paprika, coriander, cumin, turmeric, and place in bowl and add salt and then immersion blend until it’s a paste. If pot looks dry, add another 1 Tbsp. oil. Add curry paste to pot (still over medium-high heat) and cook, stirring often, until paste is slightly darkened in color and beginning to stick to bottom of pot, about 5 minutes.
