good morning Hank,
I understand your problem in having difficulties to find these species, I have the same.
In the Netherlands it's easy to get because there are many specialized so called 'toko's ' which are selling Indisch-Chinese food and spices.
All the (fresh) spices are also available here but what is the name of these herbs.
For example, I really like to buy a pot of sambal (brandal or badjak etc.) but I'm afraid I have to cook it myself.
Just try to find it first in a big grocery like SM, LKK, Caisano?
My family in the Netherlands is originating from Indonesia (Dutch Indies), so I am used to have a good indisch meal, but am also lazy to cook myself, haha.
Fiber glass insulation, things like that I remember in hardware stores like Handyman in LKK or CITI market along Gusa Highway or probably any big hardware store where they sell materials for building your house.
regards,
Sandy Rijskamp
