For a richer flavor, use coconut milk instead of chicken broth. If you don't have fresh lemongrass, you can use lemongrass paste, but the flavor will be slightly different. Look for it in the produce section of your grocery store. Adjust the amount of habanero pepper to your spice preference. For a milder curry, remove the seeds and membranes before mincing. Serve hot over jasmine rice or with naan bread for dipping.
