Thanks. I am certainly more familiar with those ingredients.
I once combined (Thai takeout) the lemongrass soup and the coconut soup and that was good. One recipe included lemon grass--I guess you can experiment.
I just don't want another 'Calypso Salsa'/very, very hot experience.
The Doc Chey's Noodle Palace makes such good coconut soup I should just buy theirs but --it is something that would be very tasty on a cold, rainy night--so I will 'Give It a Go'.
