Heat oil in a large skillet over medium heat.
Add shallots and garlic and sauté until soft and fragrant.
Add ginger, red pepper flakes and curry paste. Stir to combine.
Pan fry for about 30 seconds. Add coconut milk, lime juice and salt. Bring to a gentle boil.
Add shrimp to the sauce, stir and let simmer on medium heat until shrimp just start to turn pink.
Add mussels and cover skillet with lid. Let cook over medium heat for about 4-5 minutes. Shake your skillet a couple of times (with the lid on) to ensure even cooking.
Remove from heat and take off the lid. Discard any mussels that did not pop open.
Serve straight out of your skillet or transfer to a large serving dish and top with a shower of chopped fresh basil and cilantro. Serve over pasta. Enjoy!
